This reverts commit 950cc851.

Update release process

See merge request !297

This change improves version management between the gem and GLQL core
by using explicit tag-based dependencies instead of tracking the main branch.

Changes:
- Update gem's Cargo.toml to use tag-based dependency (tag = "v0.20.9")
  instead of branch-based (branch = "main")
- Modify release script to automatically update the tag reference when
  creating a new release
- Update config.toml comment to reflect tag-based approach

Benefits:
- Explicit version coupling: gem v0.21.0 clearly references GLQL v0.21.0
- Version stability: gem won't pick up unrelated changes from main branch
- Independent release timing: gem can stay on older GLQL versions if needed
- Better reproducibility: builds always fetch the exact same GLQL version
- Local development unchanged: still uses patch override for testing

Note: GLQL must still be tagged before the gem can reference it, but this
approach provides clearer version relationships and more control over
which GLQL version the gem depends on.
