make the username query from the ssh command case insensitive

[fightingirjsh2]

Pretty much the title. I am in IT implementing warpgate with authentik to improve our ssh workflow and our active directory usernames are a mix of capitals and lowercase. Normally with ssh case is not an issue but with warpgate it has to be exact. It would be a nice toggle to have or just default to case insensitive like many Linux distros now.

I'm not sure about the implementation details but this issue would help with my use case at least.

Interestingly, after upgrading to 0.52.2. CLI ssh login still fails based on case sensitivity. It works with my username with caps, but when I leave all lowercase i get the message [1] Browser authentication was not confirmed please try again.
