[ViacheslavKudinov]

Resolves #2865

Before the change?

• 🤷‍♂️ it could be the situation when one PR will get more than one label as the changes can be based on branch name and changed files on specific paths covered by config.
  It may result that the same PR will come under more than one release category.

After the change?

• ✅ lets keep only branch name based labeling for some time and then decide if we would like to extend to path-based labeling again
