feat: added patreon oidc provider

[AUSBird]

This PR is intending to implement another OIDC provider for Patreon to Kratos since Patreon has non-standard paths to it's auth and token endpoints and doesn't have a discovery endpoint

While I was there I also added missing OIDC provider types to a code comment to update it with missing ones (Not sure if it matters or no)

Related issue(s)

I never made an issue to for this because it's just a new provider and the issue templates only has one for non-trivial features. (If I should have made one anyway, tell me for next time :) )

I did bring it up months ago in slack but never got any response,

PR for Documentation: ory/docs#1211

Further Comments

This is my first ever go at golang so feel free to give me feedback on anything but I do ask you simplify a bit and if possible can I get pointers to documentation when comments are made to help me learn :)

I don't know how or where that unit test broke, I had a look where it said and nothing around it seems to obviously connect to my changes.

Can someone please give me a small pointer to solving it?

Edit: Merging master in fixed the test

Nice, this looks very good 👍
I just have one minor remark.
