Fix gem dependency declaration

Dependabot updated openid_connect despite this being restricted in our
Gemfile. Now, all future updates downgrade openid_connect again to
satisfy our requested version.

I couldn't find any good reason not to upgrade openid_connect though and
since that's the version we already have, let's keep it and just remove
the restriction. Then bundler doesn't downgrade any more and updates are
performed well.
