[DOC] Update the Analyze app performance content

[knylander-grafana]

The Analyze app performance using Pyroscope needs some additional information. Because the content isn't complete, the page is set to draft: true so it doesn't appear in the documentation.

File to update: docs/sources/ingest-and-analyze-profile-data/analyze-profiles/_index.md.

The page currently lists these examples:

• Comparing two different git commits before and after a code change
• Comparing Staging vs production environments to identify differences in performance
• Comparing performance between two different a/b tests or feature flag experiments
• Comparing memory allocations between two different time periods before and after a memory leak
• etc

To do:

• Write a walk through for how to use Pyroscope to analyze app performance (or other relative data)
• Provide examples and screenshots for the examples
