[receiver/gitproviderreceiver] add repo branch and contrib count metrics (open-telemetry#28885)

**Description:** 
Second PR for the gitprovider receiver to add functionality for repo,
branch, and contributor count metrics. There will have to be more than 4
repos given the amount of metrics collected in this scraper, so we're
only adding these 3 to show capability and foundation.

open-telemetry#22028 

**Testing:** 
Basic tests included for the functionality. 

**Documentation:**
Documentation updated to include information about configuration of
metrics and the metrics that are currently available alongside targets.
