#3334257: Update Bootstrap Layout Builder module from 2.0.1 to 2.1.1

Steps to reproduce

Scenario: Check if a site admin can create a landing page and add sections to it with different container types                                                                                                                                                                                                   
    Given I am a logged in user with the "Site admin" user                                                                                                                                                                                                                                                          
    When I go to "/node/add/landing_page_lb"                                                                                                                                                                                                                                                                        
    And I wait                                                                                                                                                                                                                                                                                                      
    Then I should see "Create Landing page (Layout Builder)"                                                                                                                                                                                                                                                        
    When I fill in "Test Landing page (Layout Builder) by Site Admin" for "Title"                                                                                                                                                                                                                                   
    And I fill in "Test Landing page (Layout Builder) description" for "Page description"                                                                                                                                                                                                                           
    And I select "published" from "Save as"                                                                                                                                                                                                                                                                         
    And I press the "Save" button                                                                                                                                                                                                                                                                                   
    And I wait                                                                                                                                                                                                                                                                                                      
    Then I should see "Landing page (Layout Builder) Test Landing page (Layout Builder) by Site Admin has been created"                                                                                                                                                                                             
    And I should see "This layout builder tool allows you to configure the layout of the main content area."

    And I wait for AJAX to finish                                                                                                                                                                                                                                                                                   
    And I select the "Primary" section background color

The automated functional test will stop at this point with the follow screenshot by the robot
It can not see the section background color, as it is under the Bootstrap Navigation Tabs

Before the update of Bootstrap Styles .. and Using the Layout Builder UX

After the update of Bootstrap Styles .. and Using the Layout Builder UX

Only using Bootstrap Styles ... "NO" Layout Builder UX styles

After the update of Bootstrap Styles and Bootstrap Layout Builder
Having a sticky Bootstrap Navigation Tabs is failing the functional automated testing with media and small screens.

Proposed resolution

• Switch to relative position for bs_nav-tabs Bootstrap Navigation Tabs
• Keep the Layout Builder UX style for the ui-resizable-handle UI Re-sizable Handle for the ui-dialog-off-canvas UI dialog off canvas
