Out of band auth flow not working

[ianlewis]

Description

The auth process in gitsign outputs a URL you should be able to open in the browser to get a verification code, but the oauth2 server redirects to localhost after logging in. In this case localhost is not accessible so the auth flow cannot complete.

$ git commit -m "foo"
error opening browser: exit status 3
Go to the following link in a browser:

         https://oauth2.sigstore.dev/auth/auth?access_type=online&client_id=sigstore&code_challenge=P69wZPuonUkCS2-LAp26XO-Ndw3GzeyATyuixsMRz7c&code_challenge_method=S256&nonce=xxx&redirect_uri=http%3A%2F%2Flocalhost%3A45077%2Fauth%2Fcallback&response_type=code&scope=openid+email&state=xxx
Enter verification code:

Version
