Get system fonts on dropdown

[AM-I-Human]

I notice that if I run /client:set termfontfamily="My Nerd Font Mono" I can use my system fonts without issues, maybe it is possible to add something like this: https://github.com/princjef/get-system-fonts. If installing is the issue the code is right here: https://github.com/princjef/get-system-fonts/blob/232af282ee66c51c0335a01ff07e759d53ce8ddd/src/index.ts
