fix: output report generation

[grantcox]

This PR contains a:

• bugfix
• new feature
• code refactor
• test update
• typo fix
• metadata update

Motivation / Use-Case

The changes in #300 broke the outputReport functionality, specifically:

-      const content = outputReport.formatter
-        ? loadFormatter(stylelint, outputReport.formatter)(results)
-        : formatter(results);
+      const content = outputReport.formatter;
+      loadFormatter(stylelint, outputReport.formatter)(results, returnValue);
+      formatter(results, returnValue);

means that the content that is written to the output file, is always just the .toString() of the outputReport.formatter itself. For example:

outputReport: {
  filePath: "stylelint-report.json"
  formatter: "json",
}

> cat stylelint-report.json
json

I have not added additional tests for this change, as I am unable to run the existing test suite:

Please note that the existing output-report.test.js test cases do not assert the content of the output file at all, just that it was created. This will be why the tests did not catch this regression when it occurred.
