Should the templates be more specific with Azure Cosmos DB?

[seesharprun]

Azure Cosmos DB is a suite of database APIs: https://learn.microsoft.com/azure/cosmos-db

It includes:

• Azure Cosmos DB for NoSQL
• Azure Cosmos DB for MongoDB
• Azure Cosmos DB for MongoDB vCore
• Azure Cosmos DB for PostgreSQL
• Azure Cosmos DB for Apache Cassandra
• Azure Cosmos DB for Apache Gremlin
• Azure Cosmos DB for Table

At a minimum (short-term), I want to create a pull request to update the label from "Azure CosmosDB" to "Azure Cosmos DB" which is the official product name. I created a quick-fix PR in #460

Long-term, I would recommend adding some of the sub-service tags so we can be more specific about templates we're hosting on the site. I didn't feel comfortable generating a PR about this issue without further discussion. Most new samples are in the API for NoSQL, Table, PostgreSQL or MongoDB, so adding just those would go a long way towards splitting up the samples. But, I don't want to pollute the taxonomy. What does your team think?
