Managing the Script Loader installation

## Summary
A few questions about the [Script Loader](https://www.docs.developers.amplitude.com/data/sdks/sdk-quickstart/#script-loader) installation:
- In the provided script I see the URL `https://cdn.amplitude.com/libs/analytics-browser-2.0.0-min.js.gz` and integrity hash. Does this mean that this installation way offers usage of the outdated version (2.0.0) and doesn't support updates?
- Is there a way to load `analytics-browser` from CDN directly (without wrapper)?
