LibSSH2 update

The new LibSSH2 1.11 update brings a few interesting changes.

Adds support for encrypt-then-mac (ETM) MACs
Adds support for AES-GCM crypto protocols
Adds support for sk-ecdsa-sha2-nistp256 and sk-ssh-ed25519 keys
Adds support for RSA certificate authentication
Adds RSA-SHA2 key upgrading to OpenSSL

The most importing is that newer SSH servers use newer SHA2 hashes and newer encryption algorithms. Since more and more servers disallow older encryption standards and require the newer ones, you may want to update to the new plugins soon to prevent connection problems.

Included in MBS FileMaker Plugin 13.3 and MBS Xojo Plugins 23.3, currently in pre-release testing.
