Removed outdated torch version checks from transform functions

[nkaenzig]

Fixes #8348

Description

Support for torch versions prior to 1.13 has been dropped, so those 1.8 version checks are not required anymore. Furthermore, as reported in the issue description, those checks led to unstable behaviour when using certain transforms in data pipelines.

I think this is good, if we're through the tests and blossom we can merge, thanks!

The DCO issue should be fixable through the instructions it gives for a remedial commit.

@ericspod Thanks for the review. After a couple of attempts I managed to fix the DCO :D

@ericspod @KumoLiu Thanks a lot for the quick review & merge process. I wanted to ask if it would be possible to do a new release soon which includes those changes?

Hi @nkaenzig we weren't planning a release soon since we're working on things for a proper 1.5 release. We've removed things already that shouldn't go until 1.5 so a patch release now may be a problem. If you want the fixes to use immediately you can install MONAI from the git repo using pip or install monai-weekly.
