Currently, the github docs-pages workflow is triggered only when changes are merged to the master/enterprise branches, which means that in the case of changes to a release branch, for example, a fix to branch-5.4, or a branch-5.4>branch-2024.1 merge, the docs-pages is not triggering and therefore the documentation is not updated with the new change,
In this change, I added the `branch-**` pattern, so changes to release branches will trigger the workflow
