pin nightlies to 20250122 (#1608)

Summary:

There are test failures with the 20250123 nightly:

```
        if not output_graph.export:
            if not self.guard_manager.check(output_graph.local_scope):
                reasons = get_guard_fail_reason_helper(
                    self.guard_manager,  # type: ignore[arg-type]
                    output_graph.local_scope,
                    CompileContext.current_compile_id(),
                )
>               raise AssertionError(f"Guard check failed: {reasons}")
E               AssertionError: Guard check failed: 0/0: ___check_metadata_140011526812544_c0/0
E
E
E               You can suppress this exception and fall back to eager by setting:
E                   import torch._dynamo
E                   torch._dynamo.config.suppress_errors = True

/home/vasiliy/.conda/envs/pt_nightly_20241006/lib/python3.11/site-packages/torch/_dynamo/guards.py:2468: AssertionError
```

Pin to the previous day for now until the problem is fixed in
