 In [changeset:"53022" 53022]:
 {{{
 #!CommitTicketReference repository="" revision="53022"
 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.

 References:

 - OpenSSH 8.2 release notes
 - OpenSSH 8.7 release notes
 - OpenSSH 8.8 release notes

 Follow-up to [8865].

 Props richybkreckel, dd32, SergeyBiryukov.
 Merges [52807] to the 5.9 branch.
 Fixes #52409.
