Add workflow to automatically uplift tt-forge-models in tt-forge-onnx

[chandrasekaranpradeep]

Summary

Add a GitHub Actions workflow that uplifts the tt-forge-models submodule in tt-forge-onnx on a daily schedule, similar to the existing tt-mlir uplift workflow. tt-forge-onnx is currently out of date with tt-forge-models; this workflow will keep the submodule up to date by opening uplift pull requests automatically.

Dependency

This work should be done after Unify model and input loading via tt-forge-models repository (Issue #3183) is completed.
