[Feature]: VSCodium support

[euven]

Is your feature request related to a problem? Please describe.
At the moment it doesn't look like this plugin works with codium. It looks like the plugin watnt's to save settings to .vscode, instead of the codium path?

Describe the solution you'd like
Support VSCodium

Describe alternatives you've considered
I'm just using nix-shel, then opening codium from there. Might look into the nix direnv support too.

I tried symlinking the directories as well, no dice.

I've just come back to this extension after a few years (because of #97) and it does seem to work with Codium now.
