Issue

When building a wheel, the name of the data section should be {distribution}-{version}.data, where {distribution} is the PEP 503 normalisation followed by replacing - with _.

See Binary distribution format

Currently the data section is using _package.name rather than distribution_version(_package.name) (https://github.com/python-poetry/poetry-core/blob/d98aa6e49f614f7631667da3144d7b291c7e7889/src/poetry/core/masonry/builders/wheel.py#L310)
