Issue:
Allow configuration in pyproject.toml under `tool.argiadne-codegen`
First of all, thanks for this great project!

AFAIK, the official spec recommends that additional config for specific tools is tracked within the tools table of the pyproject.toml file (i.e. `tool.argiadne-codegen`) . https://peps.python.org/pep-0518/#tool-table. 

While the its more of a nuisance then a real problem, right now my linters are complaining about an unknown key in the file.

If you think its worthwhile to change this, I'd be happy to submit a PR to support either both keys, or change the current behaviour.
