RalfG/python-wheels-manylinux-build: v0.6.0

Add Python 3.11 to default versions to be build (#54) Add Python 3.11 to test workflow, drop 3.6 (#57, #59) Remove Python 3.6 from default versions (#59) Fixes the name of the .whl files to look for in the find command for auditwheel repair from *-linux*.whl to *-manylinux*.whl (enables support for Poetry) (#56) Makes auditwheel show stderr output to the $failed_wheels file (#56) Ignores non-breaking "error" This does not look like a platform wheel when run against pure python wheels, which can be created, for example, under pypy when the build process doesn't produce compiled code (#56) Checks if the $failed_wheels file is not empty instead of whether it exists before exiting with an error (#56) Thanks @agates, @skshetry, and @EwoutH
