[DOC] Add doc to explain how someone uses Pyrocope

[knylander-grafana]

Lots of good info on configuring Pyroscope, but nothing on what you can do with it.

Consider adding even one page that provides a list of the most commonly used things people do with Pyroscope -- even if this is a link off to Grafana or Grafana Cloud.

For example, possibly two new pages:

• Visualize your profile data
• Analyze your profile data

Draft content is here: https://grafana.com/docs/pyroscope/next/ingest-and-analyze-profile-data/

It still needs to smoothed out and sorted.

The only thing that's missing is a screenshot with labeled elements.
