Show In Explorer does nothing when the build folder no longer exists in the Build Analysis Window

Steps to reproduce:

1. Create a project and build it.
2. Open Window > Analysis > Build Analysis.
3. Outside Unity, delete (or move) that build's output folder on disk.
4. In the Build Analysis window, right-click the build entry (still listed) and choose "Show in Explorer" (also available in the Build Details section).

Actual results: Nothing happens - no file browser, no dialog, no Console message. The entry stays listed and the menu item stays enabled, so there is no indication the folder is gone. 

Expected results: The Editor gives feedback when the folder no longer exists - a dialog / Console message, and/or the "Show In Explorer" action disabled for entries whose path is missing.
