Replace minified apexcharts by full version

Using minified Javascript code raises packaging issues [1].

Replace with the full version of ApexCharts v4.7.0 [2], which is the
last release under MIT license. Newer 5.x releases are under a custom
license [3].

Included the full MIT license at the top of the vendored file to ensure
we comply with the distribution terms.
