…igured GetTokenSourceFromConfig/Env legitimately return a nil oauth2.TokenSource when nothing is configured. GetAccessToken called Token() on that nil source, panicking deep inside Clone instead of returning a usable error. Fixes updatecli#8297 Signed-off-by: Loïs Postula <lois@postu.la>

Tradeoff
The error is still surfaced inside
Clonerather than at SCM init time. Surfacing it earlier would be a larger change touching the GitHub SCM init path; this PR is the minimal fix to stop the panic.Potential improvement
Detect "no token configured" at GitHub SCM init time and fail fast with an actionable message before reaching
Clone.
