Lists and nested lists are not roundtripable

[buuhuu]

When nesting lists the text of a list is wrapped in an additional <p>.

See the test case in https://github.com/adobe/helix-html2md/compare/nested-lists-roundtrip

Examples:

<li><a href="#" title="Navigate to Text 1">Text 1</a></li>

becomes

<li>
  <p><a href="#" title="Navigate to Text 1">Text 1</a></p>
</li>

and when you input <li><p>...</p></li> ?

That works, yes. If we do this, we have different representation than content coming from doc-based authoring.

(We took the html from https://main--kuckstdu--msagolj.hlx.page/TipsAndTricks/unbenanntes-dokument as input)

It seems that the spread out of lists containing block elements is intentional and I would agree to some extend. However, I think it is more important to produce the same markdown a doc-based project would use.
