examples are being installed to site-packages after setup.py fixes

[benkohler]

I'm adding 1.19.4 to gentoo repos and our python checks have started throwing an error:

• python3_11: running distutils-r1_run_phase distutils-r1_python_install
  • The following unexpected files/directories were found top-level
  • in the site-packages directory:
  • /usr/lib/python3.11/site-packages/examples
  • This is most likely a bug in the build system. More information
  • can be found in the Python Guide:
  • https://projects.gentoo.org/python/guide/qawarn.html#stray-top-level-files-in-site-packages

The very last commit in 1.19.4 modifies setup.py to use an exclude rather than an include, I think we need to add examples to the list after all the test matches.

Thank you for flagging this, and for the PR to correct - it is merged in v1.19.7
