Handle GitHub "Repository access blocked" error (#13648)

* Handle GitHub "Repository access blocked" error

We've been seeing a lot of these errors on DEV, and it's a pretty
reasonable expectation that if we're being blocked from seeing them
using the user's OAuth access token that this isn't temporary.

* Re-raise so we don't swallow this error

* Constant name != company name???!?!?!
