Handle logout URL

Any update or workaround for the issue.

The patch in the MR will fix up the parameters and fix the issue. This requires a patch from ✨ Add native support for Auth0 Needs review : https://www.drupal.org/files/issues/2023-03-29/openid_connect-3327237-26... → .

I'll merge the MR when they have theirs merged. Marking "postponed" until they do. Until then, their patch plus this one will fix the issue. Note: you have to include the logout redirect URL in the login.gov application. 🐛 Show the logout redirect URL in the plugin form Needs review adds the logout redirect URL to the plugin edit form for easy copy/paste.
