missing gems to work with new key encryption type

[novozhenets]

After 0d78e2d
I was getting errors about failed authentication via key

net-ssh-7.0.1/lib/net/ssh/authentication/ed[25](https://github.com/novozhenets/trackfolio-backend/runs/7365266070?check_suite_focus=true#step:4:26)519_loader.rb:19:in `raiseUnlessLoaded': OpenSSH keys only supported if ED25519 is available (NotImplementedError)
net-ssh requires the following gems for ed25519 support:
 * ed25519 (>= 1.2, < 2.0)
 * bcrypt_pbkdf (>= 1.0, < 2.0)

Issue is described here net-ssh/net-ssh#565

This should probably be added to README, it took me quite some time to figure this out

I can confirm I had the same problem, and adding both gems to my Gemfile solved the issue

[Haguilar91]

I can also confirm that fixes it, but my error was different.
