Drop optional shap dependency

This PR drops the shap library from the list of test dependencies, which is an optional dependency used only for one test in model builders from lightgbm.

Motivation: this shap library doesn't have python3.14 support, and is the only dependency blocking a transition for scikit-learn-intelex:
conda-forge/shap-feedstock#101

It appears they might have repeated issues getting builds for new python versions when they release due to their numba dependency:
shap/shap#4236

Hence, better to drop it altogether and maybe add it back in the future if we see that it gets builds for python3.15 within a reasonable period after its release.

Hi! This is the friendly automated conda-forge-linting service.

I just wanted to let you know that I linted all conda-recipes in your PR (recipe/meta.yaml) and found it was in an excellent condition.

Hi! This is the friendly automated conda-forge-webservice.

I tried to rerender for you but ran into some issues. Please check the output logs of the GitHub Actions workflow below for more details. You can also ping conda-forge/core (using the @ notation) for further assistance or you can try rerendering locally.

The following suggestions might help debug any issues:

• Is the recipe/{meta.yaml,recipe.yaml} file valid?
• If there is a recipe/conda-build-config.yaml file in the feedstock make sure that it is compatible with the current global pinnings.
• Is the fork used for this PR on an organization or user GitHub account? Automated rerendering via the webservices admin bot only works for user GitHub accounts.

CI failures are about this test:

tests/test_memory_usage.py::test_memory_leaks[(2000, 50)-NuSVC

It is checking for memory leaks, but the test is not well designed and can fail in cases in which no leak occurs. I think it can be ignored.
