[polari] ci: Add syntax check

[Marge Bot <marge-bot src gnome org>]

commit b2cb60a7c77b10ce032ee9c905f0207062a4bafb
Author: Florian Müllner <fmuellner gnome org>
Date:   Fri Feb 18 03:39:38 2022 +0100

    ci: Add syntax check
    
    Pull in gjs-ci-tools, which includes a script to perform a simple
    syntax check similar to `js91 --compile-only`, then run the script
    during CI to replace the previously removed compile-time tests.
    
    The script uses gjs instead of the SpiderMonkey shell, which means
    it will always use the same engine version with the same feature set
    as gjs.
