[Task]: Reduce bundle size via react-syntax-highlighter

[elliotBraem]

Overview

highlight.js/lib and refactor both come from react-syntax-highlighter (used in near-social-vm), and amount to 400+ KB.

This was attempted to be solved with NearBuilders/VM#feat/syntax-highlighter, but will require more attention.

Details

react-syntax-highlighter is used for representing Markdown code blocks, and so it only needs to use the most popular languages.

Acceptance Criteria

• All tests pass
• Reduced package size, show benchmarks and improvements in PR
