userauth_pubkey: signature algorithm ssh-rsa not in PubkeyAcceptedAlgorithms [preauth]

[commonism]

OpenSSH 8.8 deprecated using ssh-rsa.
golang/crypto/ssh does not play nice with OpenSSH 8.8.

Using tobischo/gocrypto@a878079 it works.

go mod edit -replace golang.org/x/crypto=github.com/tobischo/gocrypto@a878079a19cdba9b9da3ce57de2c4c9cb43b7ea3
go mod tidy
