### What does this PR do?

Type of change: Deprecation of dead code <!-- Use one of the following:
Bug fix, new feature, new example, new tests, documentation. -->

Deprecation warning already added in 0.44 as per 1-release deprecation
policy

GradNAS only works for Bert and GPT-J and we dont actively maintain it
or test it. Keeping it creates an expectation that it works plus it adds
one more option for user to choose from. We already have much better
pruning algorithms (Minitron and Puzzletron) for LLM pruning already
hence removing GradNas.
