To ensure functionality on all platforms, the "Test Go" GitHub Actions workflow runs the tests on Windows, Linux, and
macOS. This is done via a "job matrix", which runs the three jobs in parallel.
By default GitHub Actions uses a "fail fast" behavior for job matrixes, where all in progress or pending jobs of the
matrix are immediately canceled upon failure of any job.
The benefit of this "fail fast" behavior is efficiency in the case where a failure is universal and those other jobs
were certain to eventually fail. However, in other cases a failure is either specific to the configuration of a single
job (e.g., a Windows-specific bug), or a spurious result of a transient network outage. In the latter case, canceling
the other jobs is very harmful. Running the jobs for the other operating systems would highlight the nature of an
OS-specific failure for the contributor. Canceling other jobs due to a transient failure means all those jobs must be
reran instead of only the specific job that suffered the failure.
The workflow is hereby configured to disable the "fail fast" behavior. All the matrix jobs will now run even if one of
them has failed.
