Feature/version fixup

[davidorme]

Description

The package version in virtual_rainforest.__version__ now tracks the version set by poetry in pyproject.toml

Fixes #90

Type of change

• New feature (non-breaking change which adds functionality)
• Optimization (back-end change that speeds up the code)
• Bug fix (non-breaking change which fixes an issue)

Key checklist

• Make sure you've run the pre-commit checks: $ pre-commit run -a
• All tests pass: $ poetry run pytest

Further checks

• Code is commented, particularly in hard-to-understand areas
• Tests added that prove fix is effective or that feature works

Nice!

But what about the documentation? Can you get the version in Sphinx the same way?

Oddly, that failure didn't happen when running pytest locally. I don't know why the local mypy didn't go looking in the docs tree. I've updated conf.py to use the new API for the version number and all should be well.
