github "Quick/Nimble" ~> 8.0.1

Running carthage build --no-skip-current && carthage archive to archive binaries from Mantle GitHub actions:

Carthage Output

*** Skipped downloading Nimble.framework binary due to the error:
8
	"API rate limit exceeded for 199.7.166.17. (But here's the good news: Authenticated requests get a higher rate limit. Check out the documentation for more details.)"
…

Actual outcome Carthage did not have an GITHUB_ACCESS_TOKEN set and got rate-limited.

Expected outcome Carthage should have used the GITHUB_TOKEN from the GitHub Actions environment instead.
