* chore: fix existing vitest type tests

These weren't asserting anything, and vitest type tests weren't enabled.

* build: add missing `skipLibCheck`

This is a tough one to explain. This was a latent issue due to a confluence of things:
- we don't explicitly do type checking in this repo
- instead we rely implicitly on the fact that we use tsup in part to build `.dts` files, which
  performs type checking
- but tsup type checking behaves slightly differently than just running `tsc` in various little
  ways, largely because it's scoped per entrypoint
- we weren't setting `skipLibCheck: true` in the `tsconfig.json`, which seemed reasonable as there
  were no errors inside `node_modules/`
- now when I went to set up vitest type tests, this started type checking some stuff under the hood,
  and this failed with type errors inside `node_modules/`, despite it using our `tsconfig.json`
- it turns out this is because the tsup type checking approach was not encountering these errors;
  you can confirm this by running `npx --package=typescript tsc --noEmit` in `packages/functions/`

So, TL;DR: we had a latent necessity for `skipLibCheck` obscured by our weird implicit type checking via `tsup --dts`.
