Filesystem API: Include the `ssh-ed25519` public key signature algorithm as an alternative to `ssh-rsa`. 

The `ssh-rsa` signature algorithm is disabled by default as of OpenSSH 8.8, which breaks SSH2 uploads in WordPress on modern systems. `ssh-ed25519` is one of the suggested alternatives, supported since OpenSSH 6.5.
