DEV: Introduce version_bump rake tasks (#22817)
This commit introduces five rake tasks to help us with version bump procedures:

- `version_bump:beta` and `version_bump:minor_stable` are for our minor releases
- `version_bump:major_stable_prepare` and `version_bump:major_stable_merge` are for our major release process
- `version_bump:stage_security_fixes` is to collate multiple security fixes from private branches into a single branch for release

The scripts will stage the necessary commits in a branch and prompt you to create a PR for review. No changes to release branches or tags will be made without the PR being approved, and explicit confirmation of prompts in the scripts.

To avoid polluting the operator's primary working tree, the scripts create a temporary git worktree in a temporary directory and perform all checkouts/commits there.
