Add JS libraries from jslib.k6.io to jslib docs page

[heitortsergent]

Add the libraries that are listed on jslib.k6.io to the jslib docs page: https://grafana.com/docs/k6/latest/javascript-api/jslib/

The goal is not to add a full set of docs for each library, but to list them so that users can easily find them. We need to differentiate between the libraries that have a full set of docs (aws, httpx, etc.) and the ones that don't.
