📝 Description

Deprecate the experiment parameter in submit_pipeline as part of the gradual deprecation plan.

This PR emits a warning when experiment is explicitly passed, while keeping backward compatibility and existing behavior intact. The parameter remains functional in versions 1.11–1.12 and will be removed in 1.13.
