fix: Handle remote prune failures gracefully (#4295)

Wrap the git remote prune command in a try-catch block to prevent
the action from failing if the prune operation fails. Instead, log
a warning message and allow the action to continue.

Fixes edge cases where the prune command may fail on self-hosted
runners but shouldn't block the pull request creation workflow.
