Fix numpy version for py39

[rly]

Motivation

Fi #1962. Minor change on top of #1956, so I think no changelog updated is needed.

Sounds good. For the environment-ros3.yml file, do you prefer using just numpy==2.1.1 there or moving the numpy install to the pip section to use the same environment markers?

The Python version in that file is pinned to Python 3.12 (so we only test ros3 support on Python 3.12), so it should be OK.
