Outputting help text as individual lines

Beyond parsing the string into lines, how would I modify this to call `Log.Information()` for each line of help generated? It seems the API is capable of this, but I'm obviously struggling to figure it out myself.

```
static void DisplayHelp(ParserResult result, IEnumerable errs) {
var helpText = HelpText.AutoBuild(result, h => {
h.AutoHelp = true;
h.AutoVersion = true;
return HelpText.DefaultParsingErrorsHandler(result, h);
}, e => e);
Log.Information(helpText);
}
```

Start with the DisplayHelp example in the issue and inspect the HelpText.AutoBuild result and the logging call shown there. Determine how the generated help text should be split for individual Log.Information calls, then verify the output preserves each help line as intended.
