      Constructs an asset URL path from the virtual folder and path (within the virtual folder). After constructing the string (and honoring the `SymbolConstants.ASSET_URL_FULL_QUALIFIED` symbol), the result is passed through the `AssetPathConverter`.
      Parameters:
        `virtualFolder` - corresponds to a `AssetRequestHandler` contributed to the AssetDispatcher service
        `path` - a path that can be used to identify the underlying `Resource` or or re-acquire the `StreamableResource`; this will be the final portion of the URL, after the appropriate prefix (based on whether the resource is compressed or not) and the checksum for the resource
        `resource` - underlying resource for the asset path; the checksum portion of the URL is obtained from the resource
      Returns:
        path portion of asset URL, which is everything needed by the `AssetDispatcher` to find and stream the resource
      Throws:
        `IOException`
