docs: enhanced description for instrumentations in package.json

[blumamir]

There seem to be a lot of variations on what instrumentation packages populate in the "description" field of "package.json". This PR aims to align them all to one format, and rephrase them to be more useful to consume (in my opinion).

Previous texts where trivial, too long, and did not explain well enough the target for each instrumentation. I tried to include a short description on what this instrumentation targets in few words. Please share any improvements suggestions to the texts.

I also added a short section to the GUIDELINES to document to the future us, how this text is recommended to be formatted.
