Changed location of config settings file for [Varbase bootstrap paragraphs] from the [install] to the [optional] directory.

Currently varbase_bootstrap_paragraphs.settings is in install directory although Varbase Bootstrap Paragraphs is disabled in Vardoc, so I think we should move its settings file to optional directory.

This change will help sub profiles on having the option of not enabling varbase_bootstrap_paragraphs as it's a dependency for varbase_landing at the install step or not be affected by updates.

Automated Fuctional Test

  @javascript @local @development @staging @production
  Scenario: Check Varbase Bootstrap Paragraphs settings, and colours.
    Given I am a logged in user with the "webmaster" user
     When I go to "/admin/config/varbase/varbase-bootstrap-paragraphs"
      And I wait
     Then I should see "Varbase Bootstrap Paragraphs settings"
      And I should see "Available CSS styles (classes) for Varbase Bootstrap Paragraphs"
      And I press "Save configuration"
     Then I should see "The configuration options have been saved."

The list of CSS classes available as background styles for Varbase Bootstrap Pargaraphs. Enter one value per line, in the format key|label where key is the CSS class name (without the .), and label is the human readable name of the style in administration forms.

These styles are defined and can be customized in vbp-colors library that is defined in varbase_bootstrap_paragraphs/varbase_bootstrap_paragraphs.libraries.yml.

To customize the styles to fit your brand with your own theme, do the following:

1. Copy the LESS (varbase_bootstrap_paragraphs/less/theme/vbp-colors.theme.less) and CSS (varbase_bootstrap_paragraphs/css/theme/vbp-colors.theme.css) files to your own theme.
2. Override or replace the vbp-colors library in your own frontend theme. You will need to edit YOURTHEME.libraries.yml and YOURTHEME.info.yml. Refer to the documentation manual for overriding libraries in your theme for more details.
3. Edit the LESS/CSS files in your own theme to customize the styles as you wish. You will notice that the admin form will load your styles in the available "Background color" options for Paragraphs.
