[BUG] Docs table of contents sidebar generates code block as back tick marks

[xelaint]

🐛 Bug report

Current Behavior

Docs table of contents sidebar generates code as back tick marks. The styling of code blocks in heading tags also need to be updated.

1. Should we be using code blocks in markdown headings?
2. If we are going to, how do we fix this in doc gen?

Expected Behavior

Docs TOC should not display the code block back tick marks.

Minimal reproduction of the problem with instructions

What is the motivation / use case for changing the behavior?

Environment

Daffodil version: X.Y.Z
Angular version: X.Y.Z 

 
For Tooling issues:
- Node version: XX  
- Platform:

@damienwebdev @griest024 since you guys prefer to use code blocks in headings, how do we handle how it's rendered in the table of contents?

[damienwebdev]

Angular has an example here: https://angular.io/tutorial/first-app#step-1---identify-the-version-of-nodejs-that-angular-requires with the word node.js interestingly, it's different on mobile versus desktop.

I don't mind this style:

@damienwebdev yea the styling is easy to update, but how do we get the code block to render as styled code blocks instead of what it currently looks like (screenshot shows back tick marks in the toc)?

[damienwebdev]

We use https://github.com/jonschlinkert/markdown-toc to generate these here: https://github.com/graycoreio/daffodil/blob/develop/tools%2Fdgeni%2Fsrc%2Ftransforms%2Fdaffodil-guides-package%2Freader%2Fguide-file.reader.ts

We would have to play around with markdown-toc to see if we can make it escape this content.
