Revert torchvision constraint (#691)

After the newest release of
[torch==2.4.0](https://pypi.org/project/torch/2.4.0/) the issue with
`torchvision` is gone. Installing the constraint `torchvision<0.19.0`
with the mentioned `torch` version is a root cause of the following
error:
`RuntimeError: operator torchvision::nms does not exist`
