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);
}
```

从 issue 中的 DisplayHelp 示例开始，检查 HelpText.AutoBuild 的结果以及其中显示的 logging 调用。确定应如何拆分生成的帮助文本以用于单独的 Log.Information 调用，然后验证输出是否按预期保留每一行帮助文本。
