✨ Added poetry preset (for python packages)

[c4th4r5y5]

Adds the ability to generate the gitmoji-changelog on python packages that utilize Poetry. (with --preset poetry )

(I understand that the python eco-system for build-packaging tools is vast, but I've only implemented Poetry. If deemed necessary, I could also look into implementing a way to handle other python tools 👍 )

Looks good! Although I use setuptools :smile:

I am closing this PR. I will open another one soon that will support any python project that uses a pyproject.toml

The approach will be based on PEP-621 therefore it will support support any build-system that uses a pyproject.toml
