gitlab_user: update SSH keys when key material changes (#11996)
* gitlab_user: update SSH keys when key material changes
Compare SSH keys by key type and key material so comment-only differences remain idempotent while changed keys are replaced. Add unit and integration coverage for SSH key updates.
Fixes#6516
* gitlab_user: add SSH key update modes
Restore backward-compatible same-name SSH key handling by default and
add explicit update and deduplicate modes for controlled replacement
behavior.
Refs: #6516
* Apply suggestions from code review
