No support for ed25519-sk ssh key

[timhorn1]

Hello,
using ssh keys with a passphrase are working fine but not with a passphrase and a yubikey, which needs to be touched.
In the terminal I can login without any problems. I am entering the passphrase and after that confirming my user presence with a touch on the yubikey, what the console asked for.
In VSCodium, there is no way to confirm the user presence via a touch on the yubikey. I assume this is the reason it fails.
The following error output is as follows:

I would be very glad if it would be possible to use my ssh key in combination with my yubikey also for vscode!
