feat(windows): use std Command

Use std `Command` instead of `ShellExecuteW` from windows sys crate.

This change was already attempted in: Byron#25
and later reverted in: Byron#27
and it it seems that it didn't work due to incorrect usage of
`explorer` instead of `cmd /c start`.
(see helix-editor/helix#5820 (comment)
for detailed explanation).
