pyproject.toml: transfer more metadata from setup.cfg

List out all packages intead of relying on find: or find_namespaces:.
find: warns because we have cola/i18n/ and cola/icons/ that contain
data files only. find_namespaces: finds too much and includes the
contrib/, requirements/ and bin/ directories.

Avoid these issues by listing the package.
