I'm open to contributing a fix, and it looks like PR #3717 points to where in the code the verbs should be placed.

I reckon this is the document that has to be updated as well; https://github.com/microsoft/typespec/blob/main/website/src/content/docs/docs/libraries/http/reference/decorators.md

I see that there are multiple parts of the codebase that handle HTTP verbs in one way or the other as well, and with different sets of verbs supported/used, but this issue has been intentionally limited to the http library.
