SSH.NET does not work for AWS hosted SFTP servers using SFTP protocol

Similar issue related to this: #1002

It seems the host key they use by default is one that this library does not support. Who's at fault here? I'd really be surprised if AWS are using by default something that is antique or deprecated.

Relevant log entry:

{
  "activity-type": "KEX_FAILURE",
  "source-ip": "XXX.XXX.XXX.XXX",
  "resource-arn": "XXXXXXX",
  "message": "no matching host key type found",
  "kex": "ssh-ed25519,ecdsa-sha2-nistp256,ecdsa-sha2-nistp384,ecdsa-sha2-nistp521,ssh-rsa,ssh-dss"
}

The private key being used is an ED25519 one.

Please try with the latest code on the develop branch and report back as to whether it works or not.
