setuptools complaines about license classifiers

[fenugrec]

Doesn't prevent the package from building.

        ********************************************************************************
        Please consider removing the following classifiers in favor of a SPDX license expression:

        License :: OSI Approved

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

Trivial fix :

diff --git a/software/pyproject.toml b/software/pyproject.toml
index 15f0a9d..85687e9 100644
--- a/software/pyproject.toml
+++ b/software/pyproject.toml
@@ -9,10 +9,9 @@ name = "fx2"
 authors = [{name = "whitequark", email = "whitequark@whitequark.org"}]
 description = "A Python package for interacting with Cypress EZ-USB FX2 series chips"
 readme = "README.rst"
-license = {text = "BSD-0-clause"}
+license = "0BSD"
 classifiers = [
   "Development Status :: 4 - Beta",
-  "License :: OSI Approved", # " :: 0-clause BSD License", (not in PyPI)
   "Topic :: Software Development :: Embedded Systems",
   "Topic :: System :: Hardware",
 ]

But I do see the comment " :: 0-clause BSD License", (not in PyPI) so maybe this fix is not strictly correct ?

They've added it in the years since.
