Fix index using tuple for image cropping operation (#8633)

I'm getting a warning at this line:
"Using a non-tuple sequence for multidimensional indexing is deprecated
and will be changed in pytorch 2.9; use x instead of x. In pytorch 2.9
this will be interpreted as _tensor.py:1654
tensor index, x, which will result either in an error or a different
result".

### Types of changes
<!--- Put an `x` in all the boxes that apply, and remove the not
applicable items -->
- [x] Non-breaking change (fix or new feature that would not break
existing functionality).
- [ ] Breaking change (fix or new feature that would cause existing
functionality to change).
- [ ] New tests added to cover the changes.
- [ ] Integration tests passed locally by running `./runtests.sh -f -u
--net --coverage`.
- [ ] Quick tests passed locally by running `./runtests.sh --quick
--unittests --disttests`.
- [ ] In-line docstrings updated.
- [ ] Documentation updated, tested `make html` command in the `docs/`
folder.
