feat(detector-github)!: change implementation to DetectorSync interface

[david-luna]

Context

Another PR moving away from the deprecated Detector interface in order to prepare the codebase for a fix for #2320. this time is for GitHub detector.

Not doing all detectors at once:

• detectors are independent from each other
• smaller PRs for faster reviews
• other detectors have a similar approach on exceptions like the described in feat(detector-alibaba)!: change implementation to DetectorSync interface #2328

My reasons to categorize it as a refactor are:

• SDK handles both interfaces using detectResources from @opentelemetry/resources package. Ref
• it is unlikely to be used oustide the SDK or auto-instrumentations

Short description of the changes

• change detect method to be sync

@pichlermarc FYI: David was going to bring up some Qs regarding all the Detector -> DetectorSync PRs in the JS SIG tomorrow. There is some more discussion on #2328

For the record the SIG we agreed to break for non stable detectors like this one. So I'm merging this one when I can
