Cleaning md to strip links and other markup

[mairin]

This exactly matches the context in
instructlab/taxonomy#1255 per commit a4eca8b - this will improve the effectiveness of this knowledge node.

Noting the workflow I used to create this md:

1. Via @erictherobot 's wikipedia-markdown-generator tool (MIT-licensed), I ran:

> python3 wiki-to-md.py Swifties

2. This generated a Swifties.md in the md_output directory of my wikipedia-markdown-generator checkout dir.

3. I used this python script I wrote to wrap the lines at 72 (so there's 8 characters free to indent for the yaml context blocks): https://github.com/mairin/wrap/tree/main Here is how I used it:

> python3 wrap.py md_output/Swifties.md > Swifties.wrapped.md

4. I renamed Swifties.wrapped.md appropriately and filed this pr.

Much better with the wiki links removed.
