Fixes #3618.

Description

Replaces the weight clamp code in the forward method of the GeneralizedDiceLoss module with an equivalent differentiable version.

Status

Ready

I was not able to run the tests locally as some tests that do not seem to be related to my changes failed. Since the tests passed in the CI pipeline, I marked this PR as ready.

Types of changes

  • 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.
