SWR: add useSwrMutation hook

[matusgallik]

What are the steps to reproduce this issue?

1. Used the example config

What happens?

I used the example config. For react-query my POST routes produce mutation hooks, but for SWR I only get a wrapper method for the axios call.

What were you expecting to happen?

I would expect a full useSWR mutation hook to be produced for post requests. Or a mention in the documentation that indicates a different usage (e.g. I need to use useSWRMutation by myself passing a key and the generated method)

What versions are you using?

Operating System: Linux
Package Version: 6.18.1
Browser Version: Chrome something - not relevant for this issue I guess?

Can you provide a reproducer of your config and OpenApI file?

No it doesn't look like it is so marking this a new feature
