#4059 was unfortunately incomplete: some custom_url fields are currently shown, even if they are not used by the provider. Moreover the `Use Custom URLs Instead of Default URLs` is always checked by default.
Manual testing:
- go to http://localhost:3000/admin/auths
- click on `Add authentication source`
- Choose `Authentication type`: `OAuth2`
- Choose `OAuth2 provider`: `GitLab`
- verify that the `Use Custom URLs Instead of Default URLs` option is **initially unchecked**
- enable the `Use Custom URLs Instead of Default URLs` checkbox
- verify that only the fields "Authorize", "Token" and "Profile" URLs are shown (no "Email URL", nor "Tenant").
- Switch the `OAuth2 provider` to `Azure AD v2`
- verify that the `Use Custom URLs Instead of Default URLs` option is **initially checked**
- verify that only the field "Tenant" is shown (with the default "organizations").
Note: this is loosely based on the upstream fix https://github.com/go-gitea/gitea/pull/31246 which I initially overlooked.
