https://github.com/m0n9oose/omniauth_openid_connect has received a
number of important pull requests over the last year with no comment
from the maintainer.

Since OpenID Connect (OIDC) is a crucial part of our supported
authentication modes, we should maintain it. This forked gem lives in
https://gitlab.com/gitlab-org/gitlab-omniauth-openid-connect.

This fork fixes a number of items:

- Fetch key from JWKS URI if available
  (for https://gitlab.com/gitlab-org/gitlab/-/issues/225850)

- Fix handling of JWT without key ID
  (for https://gitlab.com/gitlab-org/gitlab/-/issues/326135,
  https://github.com/m0n9oose/omniauth_openid_connect/issues/72)

Changelog: fixed
