Host key algorithms rsa-sha-256 and rsa-sha-512 missing in selection box

[Tupsi]

I was trying to configure my sshd according to recommendations from the ssh-audit tool. Everything worked so far until I came to the dropdown about selcting host algorithms. It seems that not avaiable algorithms made it into the multi select, as having everything checked is not the same as "System defaults".

With system defaults you get the following from ssh-audit seen in the first screenshot.

Selecting everything in the host algo dropdown seen in picture two give you the result seen in picture three. Which kinda makes sense, because I was not able to select the now missing rsa-sha-256 and rsa-sha-512 from the dropdown.

So it would be nice, if you could add these two in one of the next patches/releases.

This was done with  23.1.5_4-amd64.

Thank you.
