Add support to "Test Go" workflow for alternative Codecov configurati…

…on paths

For the sake of efficiency, the "Test Go" GitHub Actions workflow is configured to run only when relevant files are
modified. Since the workflow uploads code coverage data to Codecov, the Codecov configuration file is one of these files.

The standard filename for the Codecov configuration file is codecov.yml, and the workflow's path filter was configured
for that filename. It turns out an alternative filename is also recognized: .codecov.yml. Two subfolders are also
supported in addition to the root of the repository as locations for the configuration file.

The workflow's paths filter was not configured for the alternative filename and locations, meaning the workflow would
not be triggered on change to the Codecov configuration in projects that use the alternative configuration file name or
locations.

The workflow's paths filter is hereby configured to recognize changes to any valid Codecov configuration file.
