Prevent the Portability Workflow from Failing Incorrectly

[CodingDepot]

Currently, the last job of the portability workflow aggregates all failures of the previous matrix build.
However, the step Process Failures returns exit code 1 when it does not find any failures, causing the whole workflow to fail.

This PR only includes a continue-on-error flag on this step to ignore its output and rather only fail the workflow when any failing workflows were found.
