In ts, introduce skipLibCheck (and sob)

Unlike a couple commits back, where I removed something because we want
to avoid others copying it, here we end up *needing* to add it because
there is not presently a story for how to handle `@types` declarations
which are in the position `console-ui` is currently:

- The consuming app/library is using `Node16` resolution, but does not
  have `"type": "module"` set, so TS interprets any unspecified module
  as being CJS.
- The `@types` package itself depends on *another* package which is set
  to operate as ESM. Here, `console-ui`'s types point to `inquirer`'s
  types, which are set as ESM.

In this situation, the direct dependency gets interpreted as CJS, and
this produces an error, because it is CJS using `import` statements and
TS complains that since it will be run as `require()` in CJS, you
should switch to using dynamic import. But: it's a `.d.ts` file! We
*cannot* use dynamic import there!

Net, there is no current workaround for this that I have found; I have
raised it in the TS Discord, and we will want to come up with a better
solution (in this case: probably just by converting `console-ui` to
publish a dual-package mode package *and* publish its own types). And
in the meantime... we will ship this with `skipLibCheck`. :sigh:
