Rework of 'pyproject.toml' to facilitate various packaging

This little "cleaning" of the 'pyproject.toml' file allows to build
correctly the python wheel file in two different ways:

- `uv build`
- `python3 -m pip wheel .`

Previously, only the `uv build` command worked. However it seems that
the python packaging macros ("%pyproject_wheel" for RPM for example) use
the `python3 -m pip wheel .` command.

Thanks to this modification, both cases are working.
