chore: enhance debugging output in PR plugin generation scripts

- Added debug statements in `generate-pr-plugin.sh` to display the tarball path, backup directory, and list of files being processed, improving visibility during deployment.
- Updated `pr-plugin-build.yml` to include output of the file list and tarball contents, aiding in verification and troubleshooting during the build process.
