Add automation for CLI and API docs #1
Description
Need to automate the process of pulling over the auto-generated CLI docs and API spec file when a new ToolHive release is cut.
The scripts/get-imports.sh script pulls the files over; need to wrap this into a GitHub workflow that opens a PR if any files have changed, and then wire it up to be called via workflow_dispatch from the toolhive repo. Related issue: stacklok/toolhive#656
