DEV: Fix api docs for default calendar (#14539)

Change the type for default_calendar to a string.

The type specified for the default calendar in the api docs wasn’t a valid type. The linting in the api docs repo reports:

`type` can be one of the following only: "object", "array", "string", "number", "integer", "boolean", "null".

This linting currently is only in the discourse_api_docs repo.
