@alerque This PR adds the missing Reveal in Explorer to the Windows platform.

This looks good to me, but I'm also not on either macOS or Windows to test it. It would be nice if we could get at least one confirmation from another party that this is working for them.

Mac functionality was already implemented before this PR, I just changed its text to match other shortcuts.

Great. Do we have 1 other Windows user that can give this a spin?

(If it goes too long with no review we'll probably just merge and let people complain if it broke, but I always try to get feedback/reviews for things I can't test even if they look sane.)

@alerque Hi, Do you think it's fine to move forward with this PR? I personally would love to use it in my day-to-day life since I'm using this functionality on my Linux machine, after all, it adds a new functionality and won't break any existing one.
