 In [changeset:"52807" 52807]:
 {{{
 #!CommitTicketReference repository="" revision="52807"
 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.
