Logging: avoid logging invalid_grant error in Sentry (#10022)

* Logging: avoid logging `invalid_grant` error in Sentry

This is a known error and it happens because the user revoked the our grant from
GitHub/GitLab UI. This commit handles this error and avoids sending it to Sentry.

* Logging: exc_info=True
