Updates a data collection.
A collection ID, revision number, permissions, and at least 1 field must be provided within the collection body parameter.
If a collection with that ID exists, and if its current revision number matches the one provided, it is updated.
Otherwise, the request fails.
When a collection is updated, its updatedDate property is changed to the current date and its revision property is incremented.
Note: After a collection is updated, it only contains the properties included in the Update Data Collection request. If the existing collection has properties with values and those properties aren't included in the updated collection details, their values are lost.
You can only call this method when authenticated as a Wix app or Wix user identity.
