[Feature]: Allow versions to be deployed to environments via miactl deploy trigger

### Describe the feature

Currently, only revisions can be deployed using `deploy trigger`. Versions should be deployable as well.

### Code of Conduct

- [x] I agree to follow this project’s Code of Conduct

Start at the miactl deploy trigger entry point and trace how revisions are currently accepted and deployed. Inspect the related tests or command code, then verify that supplying a version deploys it to an environment while existing revision behavior remains unchanged.
