Adhere to new license specification in metadata

See https://packaging.python.org/en/latest/guides/writing-pyproject-toml/#license

Note that this must drop (the end-of-life) Python 3.8, because
setuptools>=80 requires Python 3.9+ and older setuptools versions
require the license field to be a table instead of a string value.
