fix(cache): add cache busting to js files

This fix makes the cache busting work. When using asp-append-version="true" in Index.cshtml like this:
<script src="~/dist/vendor.js" asp-append-version="true"></script>

It will turn that into:

<script src="~/dist/vendor.js?v=37182361827361" ></script>

When you publish.
