[Feat]: Include a profiling article in the docs

[andaaron]

Is your feature request related to a problem? Please describe.

Add a separate article for profiling in zot.
The starting point is: https://github.com/project-zot/zot/blob/main/pkg/debug/pprof/pprof.md

This article should be linked to from:

• The API guide (the list of endpoints)
• The developer guide
• The admin guide (somewhat related to monitoring, but does not interact with the other monitoring feature)
