Releasing Realm JavaScript is a manual process, and we should be able to more most of it to CI. Pushing a new git tag should initialize the entire release process:

• [ ] Set version (CHANGELOG.md, package.json, xcode project, dependencies.list)
• [ ] Build and upload binaries for all platforms
• [ ] Publish npm package
• [ ] Upload API documentation
• [ ] Notify in #realm-releases
• [x] _{Close Jira release}
