Skip GitHub migration tests if the API token is undefined (go-gitea#21824)

GitHub migration tests will be skipped if the secret for the GitHub API
token hasn't been set.

This change should make all tests pass (or skip in the case of this one)
for anyone running the pipeline on their own infrastructure without
further action on their part.

Resolves go-gitea#21739
