failed to add aur.archlinux.org to known hosts Unknown key type "dsa"

[doums]

Hi, since recently (last week the action was still working fine), the action is failing

Adding aur.archlinux.org to known hosts` with the following error
  Unknown key type "dsa"

see https://github.com/nymtech/nym-vpn-client/actions/runs/9746853221/job/26898179272

It was probably disabled by Arch Linux itself

From https://wiki.archlinux.org/title/SSH_keys:

OpenSSH 7.0 deprecated and disabled support for DSA keys due to discovered vulnerabilities and OpenSSH 9.8 is built without support for DSA keys by default, therefore the choice of cryptosystem lies within RSA or one of the two types of ECC.

Sorry I'm not sure, does this mean that something needs to be fixed in the action side?

@doums I have removed dsa from default keyscan types. Let me know if it still error.

Sorry I missed the ssh_keyscan_types input. But yea better to have valid defaults for it.
I confirm the new release of the action solves it https://github.com/nymtech/nym-vpn-client/actions/runs/9759650071/job/26936770343

Thanks!

You should probably remove the dsa key from the README example
