Update jQuery to version 2.2.4

Thanks @effulgentsia. This is indeed patch-release-eligible since it's a patch-level update.

Hi!

Patch attached.

Looks good to me, changelog is small. Clicking around show things still work.

Needs to update core.libraries.yml

duh!

Thanks for your reviews.

New patch attached.

Path to the licence to update too.

Attached new patch.

Btw, it looks like the jquery license file previously listed doesn't exist since so much time ago.

While applying patch, there are warnings about tab indentation. I am assuming we cannot do much about it as it is a vendor js file.

<stdin>:34: tab in indent.
	isSimulated: false,
<stdin>:42: tab in indent.
		if ( e && !this.isSimulated ) {
<stdin>:51: tab in indent.
		if ( e && !this.isSimulated ) {
<stdin>:60: tab in indent.
		if ( e && !this.isSimulated ) {
<stdin>:88: tab in indent.

@swarad07,

we need not fix the vendor formatting.

Thanks everyone for the update and JS review!

After discussing the patch-level update with @wimleers, I think it's best to get this in now and use the RC phase to flush out any bugs that might occur.

Note that the vendor whitespace is correctly skipped by our coding standards checking, so we are good there:

Committed to 8.4.x and cherry-picked to 8.3.x. Thanks!
