Customer feedback | az cosmosdb sql container | Help/find could be more extensive

**Is your feature request related to a problem? Please describe.**

Yes, customers expecting help to be more comprehensive or extensive but it's currently not the case

Customer feedback:

"You should include more different examples with your commands.  For example, both az ad sp create --help az find "az ad sp create" display the same one example.  The message 'For more specific examples, use: az find "az ad sp create"' is a lie!"

"I'm trying to figure out how to do a CosmosDB SQL query. Help is not helping me. az cosmosdb sql container --help  and  az cosmosdb sql --help  don't leave me with any clues."

**Describe the solution you'd like**
1) az help would include an additional ms doc link that's specific
2) az help would provide contextual command examples(?)

**Describe alternatives you've considered**
Open to other ideas
