PyTorch changed the URL of its logo

[stevepiercy]

Unrelated to PR #2250, and according to the failed check at https://github.com/pydata/pydata-sphinx-theme/actions/runs/17194519135/job/48774620104?pr=2250, it appears that PyTorch changed the URL of its logo from:

https://docs.pytorch.org/docs/stable/_static/images/logo-dark.svg

to:

https://docs.pytorch.org/docs/stable/_static/img/logo.svg

However its logo might not appear well in light mode. PyTorch's documentation's primary navbar background color remains dark in any mode.

There's also this version in the repo:
