blog & docs: mathematical notation

Would be great to have support for rendering latex like GitHub's markdown

GitHub markdown discussion about supporting the feature:
github/markup#897 (comment)

Mathjax should be a great solution here. It has a custom right-click menu so you can copy the formula in mathml or the original tex format.

But since we're using remark, we might as well use something like this: https://github.com/remarkjs/remark-math

@fabiosantoscode let's embed this into Gatsby pipeline?

[fabiosantoscode]

@shcheklein so you mean we should use remark-math? I think it's the smarter choice here too.

[shcheklein]

@fabiosantoscode I mean I didn't check it myself, so I don't have that much of an opinion :) but it looks reasonable approach to try from the description you provided. The last thing we want is to write our own plugin again for this.

I can see gatsby-remark-katex should be a good solution for this.

I was actually looking to add hacktoberfest label but it's no longer a dvc.org issue and it's a theme issue now.
I think we are on Phase 3 of theme Roadmap
Should we consider making this repo open? cc: @iterative/websites

I think we're in Phase 2 and will be for a bit, at least until we get Tailwind and styling all sorted out, but that doesn't stop us from making the repo public and accepting contributions!
