Inconsistent requirements on requirements.txt, environment.yml, README.md, setup.py and GitHub CI

[caioolivv]

The README.md file shows the following requirements

python >= 3.8
numpy >= 1.17
scipy >= 1.6
astropy >= 4, != 5.0
CCL >= 2.7.1.dev10+gf81b59a4, <= 3
pytest >= 3.0

while requirements.txt shows

numpy >= 1.17
scipy >= 1.3
astropy >= 4, != 5.0

and environment.yml requires

python >= 3.10.2
numpy == 1.25.2
scipy >= 1.11.2
astropy == 5.3.2
pytest == 7.4.0

Also, setup.py seems to require

python == 3.8
astropy >= 4.0

Finally, from what I understand, build_check.yml tries to install the latest available (and consistent) versions of

conda-forge
gobject-introspection
pygobject
numcosmo
cmake
swig
setuptools_scm
sphinx
sphinx_rtd_theme
nbconvert
pandoc
ipython
pytest
pytetst-cov
pylint
coveralls

though I'm not sure about it, since if that was the case, all CI's would break while trying to install latest numcosmo. It then installs the requirements in requirements.txt and the latest CCL from source (which is inconsistent with environment.yml.

Aside from the obvious inconsistencies, there's probably more since libraries like numcosmo have breaking dependencies.
