Test out newer versions of PyTorch (torch>=2.0.0) for compatibility with downstream projects (SCT, ADS)

[joshuacwnewton]

Because ivadomed's inference functionality is incorporated downstream in many of NeuroPoly's projects (e.g. SCT, ADS), it must "play nicely" with other packages installed into those downstream projects.

One issue with this is that ivadomed currently pins a (relatively old) version of PyTorch, while many other deep learning packages use a newer version of PyTorch. Because of ivadomed's restriction, it often can't be installed into the same environments as other deep learning packages.

So, this PR tests out newer versions of torch (>=2.0.0), for the purposes of compatibility with libraries such as nnUnet, MONAI, etc.

Now that #1297 has been merged, I've updated this PR to remove the now-redundant commits from the kk/chore-imageio branch.

I'm starting out by testing only torch==2.0.0, but once the CI passes, I'll also try unpinning torch entirely to see if ivadomed can support the newest versions.

Although I did a sanity check on my end using a GPU, would recommend running the test suite once on the lab's GPU. Just going to pre-approve 🚀

Testing on ADS now

[mathieuboudreau]

It's going to take me a bit longer than expected to test, because since imageio was updated from version 2->3 in #1297, I'm going to have to update ADS to make it compatible with this new imageio as well (basically converting all our as_gray alls) before I can attempt to run the tests for this branch

@joshuacwnewton everything looks like it's working on the ADS side - I tested it out in this PR by pointing the installation to the latest commit: https://github.com/axondeepseg/axondeepseg/pull/739/files#diff-9efd195f4e9bfb79ccd456a1d8370fafcc4bcb0b00ea3799222667d2ae818533R29

Everything looked good using our napari GUI as well.

So it seems it's a green light from the ADS side! Thanks!

Thank you so much for your testing (with imageio as well!) ♥️
