Allow triggering Data deployments via the public API to eliminate having to sync data manually. This also includes triggering creation of Scratch Orgs via the Gearset API so that Gearset can instantly recognize them them.

The workflow we would like to automate is: feature branch is checked out which triggers a CI/CD system pipeline to create a corresponding scratch org, do a metadata deployment from a test sandbox, and sync data from the same test sandbox. This allows us to create on-demand full copies of the environment for purposes of E2E testing (inc. external integrations) and feature development that requires test data.
