CI CodeBuild is needed also for merge for documentation changes only

[tkilias]

Background

• Currently, we have the CI CodeBuild as a required check in the BranchProtection for main
• This means we need to run it successful to merge into main
• However, this also means we need to run it for documentation changes only
• The CI CodeBuild is rather slow and expensive and we would like to avoid running for documentation change only, but still keep it in BranchProtection

Possible solutions:

• have not the CodeBuild it self as mandatory in the BranchProtection, but a Github Workflow if has run for non-documentation changes
• keep it in the branch protection, but in case of documentation changes run no tests and add a commit message trigger to override this behavior
  • we could also use a skip tests commit message trigger to skip the tests
  • this could be a specific nox session
