Build Community Query

[bohn002]

Is your feature request related to a problem? Please describe.
To enable work in other items such as #547 and #610 we should have a query for communities that retrieves the list of moderators.

Describe the solution you'd like
Current use case would be adding Mod badges to username and listing Mods in a community sidebar instance.

Describe alternatives you've considered

Additional context
We should just need to make this call as part of the post detail and sidebar screens. Other cases may appear but seems wasteful to do so in the general feed screens.

Will need to most likely add a new community hook in src/hooks and pass in a community ID and either return all of the community information or adding another function that would return just the moderator list.
