Update license file reference from LICENSE to LICENCE in pyproject.toml

[williamjamir]

The humanize package does not currently include the LICEN[CS]E file when uploaded to PyPI, causing tools like pip-license to fail to detect that this package is MIT licensed.

By updating the reference to LICENCE, we ensure that the correct file is included in the package.
