Subject: [PATCH] polybar: open Google Calendar on date-module click

Wrap the date module's time string in a %{A1} action tag pointing at a
new calendar.sh, which launches the Google Calendar PWA when a browser
has installed one and falls back to calendar.google.com otherwise. PWA
desktop entries are found by Name= rather than filename, since browsers
name them <browser>-<app-id>-<profile>.desktop.
