Add failing example for Issue #151

[beau-witter]

Here is a failing example. I tried, again, to find my way through where this may be happening, but I just couldn't. Hopefully that is where you come in haha.

I do not expect this to actually merge, since this is, my virtue of #151, but hopefully it helps show the issue.

The expected.mdx is what should be the output.

But the current output looks like this:

```powershell
Write-Output "Here comes a structure of allowed options inside a codeblock"

Option 1: A single sentence description.
Default value: a good default value.

Option 2: This is more complex.
It contains two sentences.
Default value: not as good.

Option 3: This description should really not be three sentences.
I do not see why this should have.
And yet it does.
Default value: do not do this.
