fix(ci): improve workflow logging and bot notifications (#3872)

## Summary
- Link pre-commit bot comment to workflow run instead of PR for better
debugging
- Dump docker container logs before removal to ensure logs are actually
captured

## Changes
1. **Pre-commit bot**: Changed the initial bot comment to link
"pre-commit hooks" text to the actual workflow run URL instead of just
having the PR number auto-link
2. **Docker logs**: Moved docker container log dumping from GitHub
Actions to the integration-tests.sh script's stop_container() function,
ensuring logs are captured before container removal

## Test plan
- Pre-commit bot comment will now have a clickable link to the workflow
run
- Docker container logs will be successfully captured in CI runs
