Added publish check endpoint

[Michael-Dratch]

New endpoint

POST /publish-check/{checkId}

As long as the calling user is authorized to publish this check, this endpoint will

• increment the version number on the working check and update the working check document to save that new version number
• Create a new publishedCustomCheck document in the publishedCustomCheck collection with the updated version number
• Create a new snapshot of the working DMN in storage with the filename corresponding to the id of the new publishedCustomCheck document

Additional changes:

• Added missing authorization to the endpoint for updating custom checks
• The IDs of publishedCustomChecks should have the version number on them, this was missing from the function that generates the published check ids so I added it.

Small changes with the concept of ID, but overall looks great!
