Merge branch 'jc/ci-upload-artifact-and-linux32'

CI started failing completely for linux32 jobs, as the step to
upload failed test directory uses GitHub actions that is deprecated
and is now disabled.  Remove the step so at least we will know if
the tests are passing.

* jc/ci-upload-artifact-and-linux32:
  ci: remove 'Upload failed tests' directories' step from linux32 jobs
