Add license information in the package.json

[beeme1mr]

Overview

The JS SDK contribs repo is used to publish community-maintained providers and hooks. It simplifies the publishing process by providing tooling that can be reused across the mono repo. Unfortunately, while the license file was included in the published artifact, the package.json didn't include a reference to the license. That means NPM shows these files as unlicensed when, in fact, they're Apache 2.0.

### Tasks
- [ ] Update the hook and provider generator to include `apache-2.0` as the license in the package.json
- [ ] Update existing hooks and providers to include `apache-2.0` as the license in the package.json
