fix #4682 Upgrade jQuery from version 2.1.4 to 3.7.1

[Nalin-khanna]

I have tested the jQuery migration using the jQuery migrate plug-in .
The console warnings were originating from jquery-ui file , as we were using an older version of it (v1.11.4) .
I replaced it with jQuery - UI v1.14.1 (currently stable). This resolved the console warnings from jQuery migrate.
I have updated sw.js and cache.appcache to precache the new filename and updated script tag to point to new file.

• Unit tests pass
• Site behavior remains unchanged after upgrade

this closes #4682

Can you please check search? It doesn't seem to work for me.

I wasn't able to resolve this issue. After upgrading the jQuery UI file, the doSearch function seems to be getting called before it's available, likely a timing or loading order issue. It was previously undefined too, but now it's more consistent.

@Nalin-khanna The doSearch issue is an old one. #2618 can shed some light. You may have a look.
