refactor: rewrite openchrome.applescript to JXA

[sapphi-red]

Description

Converted openchrome.applescript to JXA so that it's easier to maintain.
It seems this also fixed #15880.

Tested locally and it works great! I can't highlight it, but some variables with the "AppleScript" name can probably be renamed to JXA too.

Also FWIW, I realized you need to enable this (Google Chrome) for the script to work, even with the applescript before:

Otherwise you get these errors:

• AppleScript:

openChrome.applescript:610:628: execution error: Not authorised to send Apple events to Google Chrome. (-1743)

• JXA (a little cryptic):
