Docs: Improve Examples coverage

[scottgerring]

What were you searching in the docs?

The examples that will be packaged as part of #1051

Is this related to an existing documentation section?

No response

How can we improve?

At a coarse level, we are missing example coverage of powertools-cloudformation and the coverage of the tracing, logging, and metrics library doesn't line up with the module structure.

At a fine-grained level we should check feature coverage within each example and expand as necessary.

Got a suggestion in mind?

Acknowledgment

• I understand the final update might be different from my proposed suggestion, or refused.

Adding that we should have examples using other frameworks than SAM (from the discussion here: #1074): SST, serverless fwk, terraform...

I started working on this in the cf-customresource-examples branch
