Code Issues

Remove SHA1 for support for ssh rsa signing (#31857)

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?)
