[Type2] Allow Incremental Refresh type schedules to be added via `server.schedules.add_to_schedule`

[eschranz]

Summary

For content with incremental refresh set up, allow for functionality to assign schedules as Incremental Refresh.

Description

Currently, there is no option to add incremental refresh type schedules via TSC. This functionality exists on Tableau Server when content is set up for incremental refreshes. server.schedules.add_to_schedule has an option for task_type (code), but no string option is acceptable for incremental type.

This is being worked on internally and should be available in 2023.
