Added type checks to admin-x-design-system unit tests (#20863)

no issue

- Previously we weren't running the type checks in the
`admin-x-design-system` in CI, because we only run `yarn test:unit` in
CI. This adds the typechecks to the `yarn test:unit` command so CI will
fail if the type checks fail.
