Cannot parse privateKey: Unsupported OpenSSH private key type: ssh-ed25519

[colemickens]

Describe the bug

I can't use my ed25519 key with this extension. It looks like simply bumping to the very next bugfix release of ssh2 would fix this: mscdex/ssh2#352

This extension is the most valuable extension across all of my VS Code instances. Thank you very much for developing it, and thank you for allowing it to work in Codium (whereas Microsoft's version does not).

To Reproduce
Steps to reproduce the behavior:

1. Try to connect to a host using a ssh-ed25519 key.

I have the same issue with this. I changed the ssh key generation method.

ssh-keygen -m PEM -t ed25519

I overcame that problem, but I got a new one... "all configured authentication methods failed"

When you generate an ssh file you can specify the encryption type. It seems ed25519 is not supported by Remote FS. If you create a new key and specify rsa then it will work:
ssh-keygen -t rsa -b 4096 -f ~/.ssh/your_key
Of course this would require you to update the authorized_keys on the server with the pub. If you don't have control over the server then you will prob be looking to use something other than Remote FS until it supports ed25519

hello, will you once add support of ed25519? it is more modern than rsa. would be nice to be able to use it.
