Hide version number

Problem/Motivation

Hide version number for jsframe.js

Steps to reproduce

Simply enable and use the module.

Proposed resolution

Update the fullcalendar_view.libraries.yml to allow using the local jsframe.js and only fall back to CDN version if the local file does not exist.
