enhance: Use Client Function for API Call in ParsePayload

This commit refactors the direct API call made using the ghClient
variable in ParsePayload.go to instead use the standardized
Provider.Client function. This change ensures consistency
across API interactions and enables proper metrics recording
for all GitHub API calls.
