[PORT] Remove SHA1 for support for ssh rsa signing (#31857) (#5303)

Browse source 
https://github.com/go-fed/httpsig seems to be unmaintained.

Switch to github.com/42wim/httpsig which has removed deprecated crypto
and default sha256 signing for ssh rsa.

No impact for those that use ed25519 ssh certificates.

This is a breaking change for:
- gitea.com/gitea/tea (go-sdk) - I'll be sending a PR there too
- activitypub using deprecated crypto (is this actually used?)

(cherry picked from commit 01dec7577a051d9bb30e91f6cf6653dc51a37d06)
