Migrate from Poetry to PDM

[dostuffthatmatters]

Poetry breaks very often and changes installation mechanisms frequently. Every time we do a Pyra update, something inside Poetry is broken. That is why I no longer want to depend on poetry in production environments.

With Poetry I would have to poetry export -f requirements.txt, every time, I change dependencies and include the requirements.txt in the repository. In production, I can pip install -r requirements.txt.

PDM is an alternative to Poetry and produces a pyproject.toml that is directly usable by pip. On top of that it seems to be be more stable (less breaking releases, constant installation instructions).

• Migrate pyproject.toml
• Remove Poetry from docs
• Migrate from Poetry to PDM  pyra-setup-tool#9
• Migrate CI
• Change pip install colorama in docs to just use pip install . in setup tool dir
