Replaces the manual `mkdir`, `git init`, and `git pull` sequence used for cloning the rosdistro repository with an optimized `git clone`. Key changes: - Uses `--filter=blob:none` (blobless clone) to drastically reduce the download size by omitting historical file contents. - Ensures that OAuth tokens are not persisted in the local git config. - Includes a fallback to standard clones for Git versions that do not support partial clones (pre-2.20). This change improves both performance and security during the pull request generation phase of the release process. Generated-By: Gemini 2.5 Pro Signed-off-by: Addisu Z. Taddese <[email protected]>
