Add categories to metadata

[Chuxel]

Also includes (Community) in descriptions for those not created by MS or core extension engineering teams.

@Chuxel this looks good! Do we have anything we're waiting on for merging or can I go ahead?

LGTM - thanks for adding these changes! I think adding the "Community" signifiers at a top-level makes sense. I also see based on the template that any new definitions would by default be Community but cannot be Core.

@Chuxel LGTM.

Just an observation, there are some gaps/inconsistencies when it comes to DB coverage.

mongo:

• javascript-node-mongo - category: core
• typescript-node-mongo - does not exist

postgres:

• python-3-postgres - category: core
• javascript-node-postgres - category: community
• typescript-node-postgres - does not exist

@egamma Yeah javascript-node-postgres was contributed by the community, so that is accurate. We could consider "adopting" it. For the typescript ones, I'm currently hesitant to add additional non-community maintained definitions given the volume we have already. Let's discuss.
