Recently GitHub updated the ubuntu-latest images to point at Ubuntu
22 which broke CI for ths 2.6.x branch so let's stick to Ubuntu 20
until we can sort out what was failing.
The macos-latest image recently upgraded to macOS 12. This includes
the iOS 16 SDK which deprecates some features which we're using. The
short term fix is to just keep using macOS 11 for 2.6.x.

When a single GitHub Action build fails, the other builds should not be
canceled, but instead should continue to build.
Since the matrix is setup on OS level, a failing build on one OS usually
doesn't mean it's broken for all OS.
GitHub will use these templates to pre-fill created issues and
pull requests. This should help to get people to provide better
information on issues or direct them to the forum when needed and
hint people to provide example/test code for pull requests.
