poetry.package.set_version(version)Issue
Hi! I'm trying to update poetry-dynamic-versioning to use the new plugin system (ref: mtkennerly/poetry-dynamic-versioning#39), but I've encountered several issues, and I'm currently unable to proceed because of the last one. To narrow things down, I've reproduced them using a bare-minimum sample plugin. Let me know if you'd like separate reports for each problem, but I didn't want to clutter the issue list if they're ultimately related.

Poetry declares a dependency on:

The current project's Python requirement (3.7.0) is not compatible with some of the required packages Python requirement:
- dataclasses requires Python >=3.6, <3.7, so it will not be satisfied for Python 3.7.0
Because dataclasses (0.8) requires Python >=3.6, <3.7
and no versions of dataclasses match >0.8,<0.9, dataclasses is forbidden.
So, because poetry depends on dataclasses (>=0.8,<0.9), version solving failed.

So, because poetry depends on dataclasses (>=0.8,<0.9), version solving failed.

For dataclasses, a possible solution would be to set the `python` property to "<empty>"
