This brings in Ink, our new CSS/JavaScript component library, embedding

the CSS and JavaScript on all pages. Currently it's not used anywhere,

but further changes will be moving components over to it.
Since Ink is not released, this currently requires some manual setup

during development. .npm-workspaces/ink must be symlinked to the root

of the Ink source tree, followed by npm install. Once we start

releasing builds of Ink, this symlink can be removed (though will be

needed for local development).
We make use of Ink's babel-preset to enable compilation of craft and

paint templates, easing component and element creation.
There's also a path fix to include Djblets from node_modules, rather

than the legacy .djblets symlink, in order to resolve typing issues.

Viewed some pages and verified that both the Ink JavaScript namespace

and Ink default theme CSS variables were available.
