fix: remove setup.py version bump that pushes to protected main

[busla]

Summary

• Remove the Update setup.py version and Commit version update steps from create-release job in release.yml
• Remove unnecessary pull-requests: write permission
• Merge git config and tag creation into a single step

Problem

The Create GitHub Release job failed because it tried to git push a setup.py version bump directly to the protected main branch. GitHub branch protection rejects direct pushes — changes must go through PRs with passing status checks.

Error:

remote: error: GH006: Protected branch update failed for refs/heads/main.
remote: error: Changes must be made through a pull request.

Fix

The version is already captured in the git tag and release notes, so the setup.py commit is unnecessary. Removing it avoids the protected branch conflict entirely.

Test plan

• Merge this PR, then push a content change to projects/** or cli/**
• Verify the release workflow completes all 4 jobs: generate-version, build-docs, create-release, notify-discord
