numpy on linux default to freethreaded Python in new environment

### Solution to issue cannot be found in the documentation.

- [x] I checked the documentation.

### Issue

Not sure if this is the right place to report the problem, but when running the following `conda create -n tmp numpy==2.4.2` it will pull in free-threaded Python version. Whereas 2.4.1 pulled in the non free threaded version.

```bash
❯ conda create -n tmp numpy==2.4.2
