Replace deprecated setuptools some entries in pyproject.toml #502
Description
What happened?
We are getting these deprecation warnings:

Please use a simple string containing a SPDX expression for `project.license`. You can also use `project.license-files`. (Both options available on setuptools>=77.0.0).
By 2026-Feb-18, you need to update your project and remove deprecated calls
or your builds will no longer be supported.
