Add poetry-bumpversion

[scwall]

Hello, Here is a package that should be interesting to put in the list of requirement dev: https://pypi.org/project/poetry-bumpversion/

The poetry version command only updates version in pyproject.toml file. This plugin updates version in other files when poetry version command is executed.

@scwall Thanks. I'll put it in the new release.

@scwall I need more evidence to put it in new release. Would you please tell me why should we use version in each file? Seems it cause version mismatch.
