CorrectionExtent should support .ToString() #1944
Description
Summary of the new feature
Script Analyzer rule connections use the default ToString(), which merely displays the type.
This means that to test the result of a script analyzer rule with a regex, one needs to dig into subproperties.
It also means that, say, a list of corrections in a CSV will simply look broken.
Proposed technical implementation details (optional)
[Microsoft.Windows.PowerShell.ScriptAnalyzer.Generic.CorrectionExtent] should override .ToString() method to output the correction string.
