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.

)

Add the retry plugin to automatically retry requests that fail with
server errors (5xx status codes). Configure the plugin to exclude 429
(rate limit) from retries since that is already handled by the
throttling plugin.

- Add @octokit/plugin-retry dependency
- Register retry plugin in Octokit client
- Export retryOptions with doNotRetry list excluding 429
- Apply retryOptions in GitHubHelper constructor
