feat(js): Update enriching events page

[mydea]

This updates the "Enriching Events" page in the JS docs to be more descriptive, and actually guide you through the different types of data you may add to your Sentry events.

It also:

1. Adds more details to setUser API
2. Adds more details to setContext API
3. Adds the missing sendDefaultPii option
4. Removes the "Identifying Users" page in favor of just using the setUser API page
5. Removes the "Contexts" page which was really confusing, as it mixed both explanation of contexts (which is now in setContext API page) as well as general "context" stuff like clearing scope data etc (which does not work anyhow because you need to clear the isolation scope etc... so just removing this for now).
