Do we want to handle code blocks inside block quotes? I imagine not, but we might do. Calling this out as a case we could choose to handle.

[Jefftree]

The motivation was code blocks but imo anything within the block quote ``` should NOT be interpreted as markdown and should be outputted as is with no reformatting done. That's essentially what this PR is targeting

[sftim]

Markdown blockquotes look like:

> This is a block quote
> 
> Within the block quote there could be a multiline code snippet
> ```
> echo "Hello, world
> ```

[Jefftree]

Ah sorry I mixed up the terminology.

I'm not sure if we have any examples of use cases with blockquotes, so right now I'm leaning probably not. We can re-evaluate if we see a future use case.

@Jefftree I'm happy to see this land. I can review it but you'd need to either explain how to test this, or give me an explain-it-like-I-use-Go-more-than-once-every-5-years guide to setting up a local dev environment (yes those overlap a bit).
