A required package (sip) already dropped 3.9 support in its last recipe update (6.8.6).
Also, all users of `pyqt_builder` already require only the `_python310` version.
----
Build tested on beta5 32 bits.
- Some clean up.
- Fix dependencies.
- Provide versioned script (pyqt-bundle), and a non-suffixed link
for the default Python version.
This fixes the following problems with the previous recipe version:
- Trying to do `> python3.9 -c "import pyqtbuild; help(pyqybuild)`
was failing with:
> ModuleNotFoundError: No module named 'sipbuild'
- `> pyqt-bundle --help` (after installing `pyqt_builder-1.7.0-2-any.hpkg`)
was failing with:
> importlib.metadata.PackageNotFoundError: No package metadata was found for PyQt-builder
Note: I haven't performed further testing than that.
