Using an outdated version of JS-Beautify, various bugs fixed with update

[lucacataldo]

This extension is still using JS-Beautify 1.7.4 whereas the latest version is 1.10.2

By simply updating this dependency a lot of bugs would be fixed.

One bug I've encountered that drives me crazy is that using grid-template-areas with input like this:

body {
	grid-template-areas:
		"aa aa aa"
		"bb bb bb";
}

Results in something like this after formatting:

body {
	grid-template-areas:"aa aa aa" "bb bb bb";
}

Issues like this have been fixed in js-beautify already so it would be ideal to have that updated
