pyproject and submodule dependencies

I was running the script generate_python_dependencies.sh and run into some issues, namely for the package astroid:

Could not find a version that matches astroid==2.13.2,==2.5.1,>=2.5.1 (from nomad-lab (pyproject.toml))
...

  astroid==2.5.1 (from nomad-lab (pyproject.toml))
  astroid==2.13.2 (from -r requirements.txt (line 20))
  astroid>=2.5.1 (from nexusutils (dependencies/parsers/nexus/pyproject.toml))

I am still working on what is the best solution (I will push some changes to #1156 (closed), but feel free to solve this before that branch is merged; edit: it seems the pip install with requirements.txt didnt work).

A couple of details: python3.8 was used in nexus (but this shouldn't be a problem, I think), I was checking whether setting astroid>= and typed-ast>= solves the issue, but no:

Could not find a version that matches typed-ast<1.5.0,<2.0,==1.5.4,>=1.4.0,>=1.4.2 (from nomad-lab (pyproject.toml))

There are incompatible versions in the resolved dependencies:
  typed-ast>=1.4.2 (from nomad-lab (pyproject.toml))
  typed-ast>=1.4.2 (from nexusutils (dependencies/parsers/nexus/pyproject.toml))
  typed-ast==1.5.4 (from -r requirements.txt (line 250))
