PR review help: is_differentiable_type addition stalled 3+ weeks (#189586)

Hi! I have a small open PR (pytorch/pytorch#189586) adding torch.autograd.is_differentiable_type() — a thin Python/C++ binding exposing the existing internal isDifferentiableType check to the frontend.

It’s been open 3+ weeks. The CI workflows still need maintainer approval before tests can even run, and I haven’t been able to get a review yet. I’ve tagged the code owners (@albanD @soulitzer) and added the release notes label already.

Would appreciate a nudge to get this unblocked, or any guidance on the right process for a stalled first-time contribution. Thanks!
