Skip jpeg-ls tests for Python 3.11 (#1708)

* Skip jpeg-ls tests for Python 3.11

- CharPyLS does not compile under Linux/MacOS
- also add 3.11 builds for PR builds

* Also skip pylibjpeg tests for Python 3.11

- pylibjpeg-openjpeg and pylibjpeg-libjpeg also fail to build

* Remove 3.11 PR builds for test-core-extras again
