fix: add more lenient parsing for code blocks, to accept newlines #2105

[nperez0111]

Summary

I only validated that this did what I expected, I do not think that this is actually complete, we should add tests for this specific behavior.

Closes #2105

Rationale

This allows us to more leniently parse existing code blocks from arbitrary HTML in a way which is more user-friendly.

Alright I think a single test case to cover multi-line <pre><code> elements should be enough to prevent regressions. Otherwise I think this change looks good.

The one thing I was hesitant about was that blocks generally mark newlines with a line break node, but the parsed code block content is just one big multi-line string. But then I saw that it's because of the code: true in the spec, so no issue there.

@nperez0111 do you want me to add tests for this or are you good? Also

I think this is sufficient, thanks @matthewlipski
