Mambaforge breaks cuda builds, switch to miniforge?

With conda builds [breaking](https://github.com/abetlen/llama-cpp-python/actions/runs/12246721234), it looks like the issue is that [Mambaforge is sunsetted](https://conda-forge.org/news/2024/07/29/sunsetting-mambaforge/):

> October 2024: The Mambaforge installers will refuse to install during several pre-specified date ranges (i.e., ["brownouts"](https://en.wikipedia.org/wiki/Brownout_(software_engineering))) in order to encourage users to switch to Miniforge. These dates are
> Every two weeks in October 2024 (2024-10-01, 2024-10-15)
> Every ten days in November 2024 (2024-11-01, 2024-11-10, 2024-11-20, 2024-11-30)
> Every five days in December 2024 (2024-12-05, 2024-12-10, 2024-12-15, 2024-12-20, 2024-12-25, 2024-12-30, 2024-12-31)
> January 2025: The Mambaforge installers will stop being built and distributed.

I know nothing about actions on github, but shouldn't [this](https://github.com/abetlen/llama-cpp-python/blob/main/.github/workflows/build-wheels-cuda.yaml#L66) be updated and new builds generated? Here's an [example](https://github.com/ESMValGroup/ESMValCore/pull/2556/files) of the changes on another project so doesn't look too difficult.
