Fix github CI (#478)

* fix: Use non deprecated upload-artifact action version

* fix: Use branch name in build workflow, use latest checkout action, use cd bulid as job steps doesn't preserve current directories between themselves.

* fix: remove non-existent main branch, remove deprecated ubuntu-20, removed deprecated macos-11 and macos-12, setup g++-9 and g++-10 if not exists, use latest checkout action
