Change launch_git_repository in k8s_common.yml

Problem/Motivation

In k8s_common.yml, the launch_git_repository is set to https://github.com/ms448/test.git which does not exist.

This is causing errors in BDD testing

Scenario: Create a Launch template                                              # features/tmp.20240227_062915.MKEcZM/K8s-ATDD-03-01-OperateLaunchGitTemplates.feature:6
    Given I am logged in as user "BDD_user_MKEcZM"                                # Drupal\Tests\cloud\Behat\features\bootstrap\FeatureContext::iAmLoggedInAsUser()
    When I visit "clouds/design/server_template/bdd_k8s_mkeczm/k8s/add"           # Drupal\DrupalExtension\Context\MinkContext::assertAtPath()
    And I enter "BDD_launch_git_MKEcZM" for "Name"                                # Drupal\DrupalExtension\Context\MinkContext::assertEnterField()

    And I click "GIT"                                                             # Drupal\DrupalExtension\Context\MinkContext::assertClick()
    And I should see "Configuration"                                              # Drupal\DrupalExtension\Context\MinkContext::assertPageContainsText()
    And I should see "Credentials"                                                # Drupal\DrupalExtension\Context\MinkContext::assertPageContainsText()
    And I enter "" for "Git username"                                             # Drupal\DrupalExtension\Context\MinkContext::assertEnterField()
    And I enter "" for "Git password"                                             # Drupal\DrupalExtension\Context\MinkContext::assertEnterField()
    And I wait for AJAX to finish                                                 # Drupal\DrupalExtension\Context\MinkContext::iWaitForAjaxToFinish()
    And I should see "Source"                                                     # Drupal\DrupalExtension\Context\MinkContext::assertPageContainsText()
    And I select "GitHub" from "Source type"                                      # Drupal\DrupalExtension\Context\MinkContext::selectOption()
    And I wait for AJAX to finish                                                 # Drupal\DrupalExtension\Context\MinkContext::iWaitForAjaxToFinish()
    And I enter "https://github.com/ms448/test.git" for "Git repository"          # Drupal\DrupalExtension\Context\MinkContext::assertEnterField()
    And I press "Source"                                                          # Drupal\DrupalExtension\Context\MinkContext::pressButton()
    And I wait for AJAX to finish                                                 # Drupal\DrupalExtension\Context\MinkContext::iWaitForAjaxToFinish()
    And I press "Source"                                                          # Drupal\DrupalExtension\Context\MinkContext::pressButton()
    And I should see "Branch"                                                     # Drupal\DrupalExtension\Context\MinkContext::assertPageContainsText()
    And I select "main" from "Git branch or tag"                                  # Drupal\DrupalExtension\Context\MinkContext::selectOption()
      Select option with value|text "main" not found. (Behat\Mink\Exception\ElementNotFoundException)
