Modernize images and move PHP 8.1 to legacy

PHP 8.1 is end-of-life. It is dropped from the default build and test
matrices. 8.1 and 8.1-alpine are still built, multi-arch, by the
manual legacy job (workflow_dispatch with legacy=true), together with
7.2, 7.3, 7.4 and 8.0. This replaces manual-build.yml.
