Add type annotations to `lib/utils/ujs.ts`

[jho406]

Context

Continuing on with the conversion to Typescript, lib/utils/ujs creates the handlers for UJS attributes

Issue

HandlerBuilder is a regular class, we'll need to convert this to typescript and remove the npm run lint warnings:

Note that the export at the bottom of that page:

export const ujsHandlers = ({
 ...

Doesn't actually need the parameters navigatorRef, store at all. As part of the work, go ahead and remove those two parameters too.
