change: add PATCH as a default method for CORS headers

Proposed changes

Hello 👋

Is there a specific reason that PATCH was not included as a default method for the CORS configuration? It took me a little bit of stumbling around to figure out why PATCH requests weren't working for me. It was surprising to me that this was not a default.
