fiddle refactor: improve Electron settings version table

Prior to this the table loaded all possible electron versions with no real ability to filter or search.

This PR virtualizes the list and adds input filtering.

@codebytere, looks like that change works well if the version is at the top of the list, but if you're scrolled down the list and click one of the buttons, I'm seeing it snap back to the top of the list, and am unable to scroll down at all until the operation (download or delete) has finished.
