chore(ops/modules): remove oauth2_proxy module r/6381

This was dropped from whitby itself in cl/8905, but didn't drop the
module because we were worried someone else might still be using it.

However, this relies on the "oauth2-proxy" client ID, which only has the
following supported redirect uris (as per ops/keycloak/clients.tf):

 - https://login.tvl.fyi/oauth2/callback
 - http://localhost:4774/oauth2/callback

… which means, noone can really run this properly anyways, so let's
drop it.

We can always restore it from git.
