chore(ci): Improve version bump logic and remove redundant steps

- Now correctly determines the base version for version bumping:
  - Uses the version from an existing version bump PR if available.
  - Falls back to `package.json` version if no existing PR is found.
- Ensures that the version is bumped based on the labels of the newly merged PR.
- Closes an existing version bump PR before creating a new one to prevent duplicates.
- Removed the redundant branch creation step as `create-pull-request@v7` fully manages it.
- Ensures that every new version bump PR correctly increments beyond the last one.

This improves automation reliability and prevents version conflicts. 🚀
