chore: update @material/web package.json for first release

- Set the version to what we published
- Add publishConfig section, which is required for publishing to npm @namespaces
- Pin the typescript version to ~4.7.3, because 4.8 introduced a small new typing error. It's a good idea to use ~ semver ranges for TypeScript generally, because TypeScript doesn't follow semver.
