* Add Python3.11 to the Github Actions, in the manylinux2014 build as well as the
packaging test.
I added a second image, x86_64, to the manylinux2014 build matrix - the i686
build didn't immediately pass, so I left it out.
* Move the bundled capnproto library forward to 0.10.3.
* Remove the 2010 build entirely, and update the 2014 build to include i686.
