Official information regarding AspNetCore.Diagnostics.HealthChecks package

### Description

Docs instruct us to use the AspNetCore.Diagnostics.HealthChecks package but docs also note the packages under this name are not maintained by Microsoft.

I have a couple of issues with both the docs and the project:
- the naming suggests this is or at some point was, a official Microsoft package (with it AspNetCore.* naming),
- docs clearly instruct developers to use these packages although they are not being actively developed or supported,
- namespaces for most classes within the codebase for these packages actually isn't AspNetCore.Diagnostics.HealthChecks but mostly just HealthChecks.* making things confusing,
- codebase is not being maintaned, it was left at an old version of referenced packages with security vulnerabilities, with many PRs opened but with no feedback from the author.

Microsoft official docs have been like this for a couple years now and I don't think it's appropriate.
