Notify on absent 'wezterm' executable

[thomasmore]

Should plugin somehow check if wezterm executable is available in $PATH?

A bit of context: I am working in WSL and my executable is available as wezterm.exe. Everything is perfectly fine if I add wezterm symlink to wezterm.exe, but it required a bit of investigation on my side. Also would you mind supporting WSL out of the box? I could make a PR if you are ok with this.

Definitely would be open to a PR - I also use wsl some of though, so I'll look into supporting it out of the box as well.

Thanks!
