[Bug]: MdSnippetChunker logic on Peagen is trimming README.md generations down

[cobycloud]

Describe the Bug

I noticed a lot of the README.mds were cut off, I think what's happening here is related to our chunker.

The chunker is meant to trim the explanation off the before and after of triple backticks (if present), but in the cases where there is more than one triple backtick or we want the before and after - that pattern causes issues.

Steps to Reproduce

1. Generate a project with multiple triple backticks in the README.md
