Hi,

running a setuptools/pybind11 project in Gitlab-CI (v17.1.2-ee) leads to following YAML analysis error:

jobs:make_wheels config contains unknown keys: matrix

It seems, that matrix is not a valid keyword (Docs) here, but only parallel:matrix is.

parallel:matrix, opposed to matrix is also used in the same config at another place here which makes it look like a small oversight.

YAML analysis won't complain after changing it.
