Allow for hosting of a .well-known directory

Hello,
I want to host a .well-known directory on my omg.lol page so I can use WebFinger to authenticate Tailscale with a Custom OIDC provider. I wish I could just dump static data somewhere and have it served at, for example, https://quinnlane.dev/.well-known/
It can just be static text files.

Best,
- Q
