Sometimes WSL needs an update, apparently

Note to self: Sometimes, it seems that WSL needs to be updated.  I mean, yes, obviously it does.  But apparently sometimes Windows updates will break it and you need to manually intervene.

I saw this the other day.  At some point, something got updated and when I tried to open a new WSL terminal, it would always fail with the message Error code: Wsl/Service/0x80040326.  Oddly enough, the WSL shells and processes I already had running still worked, I just couldn't start any new ones.

Luckily, the fix is pretty simple.  You just have to open up a Powershell instance run wsl --update to update WSL and then wsl --shutdown to reboot it.  That's it.  It's just annoying because that's a manual process - you still need to manually run the update, even if you reboot your computer.
