windows: Make "Reveal in Finder" always open the file explorer (#12207)

At the current moment, the "Reveal in Finder" behavior on Windows
"opens" the file using direct execution. This causes files to be opened
with whatever software they are associated with (i.e. will open Sublime
Text instead of the file explorer).

Release Notes:

- Fixed "Reveal in Finder" on Windows to open with the File Explorer.
The new behavior always opens the file explorer with the target
folder/file pre-selected.
