Packages appear to have untranspiled optional chaining ('?.') operator.

Describe the bug

Users should be able to use the package without additional webpack/babel configuration etc.

To Reproduce
See repro here:
dwjohnston/vic-gov-data-graph-take-2@d23a212

Expected behaviour

I should be able to use the packages no problems.

Actual behaviour
I get the following error:

rtl.js:1 Uncaught Error: Module parse failed: Unexpected token (8:26)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders

[dwjohnston]

Solution, when using the vue cli is to get it to transpile the dpc dependencies

dwjohnston/vic-gov-data-graph-take-2@0c60715

   //vue.config.js
    transpileDependencies: [
      "@dpc-sdp/ripple-global"
    ],

[dwjohnston]

I'm also having issues with writing tests due to this. The package comes with untranspiled .vue files - which, by default most testing frameworks etc, will not attempt to transpile code in the `node_modules_ folder.
