feat(auth): Recognize new format user tokens

getsentry/sentry#68148 changed user auth tokens, so that they now start with a `sntryu_` prefix. While the CLI correctly handles these new tokens, the CLI issued a warning when using these new format tokens.

This PR updates the CLI's auth token parsing logic to recognize the new user auth token format (in addition to the old format), so that the warning is no longer issued.
