Missing LICENSE file from wheel even when [project] is not defined in pyproject.toml

[ddelange]

Bug Description

The LICENSE file will be missing from wheels even if [project] is not defined in pyproject.toml. See oconnor663/blake3-py#69 to work around this bug and add LICENSE file to the wheel, but removed numerous entries from METADATA, and then oconnor663/blake3-py#88 to fix the latter.
