Support remark-hint inside of our codex processor

[mgan59]

Context

We would like to add support for tip, hint, and warn as potential documentation annotations inside of our markdown processing library Codex.

Actions

There is a plugin/transform called remark-hint that provides an interface with remark().

Integration should consist of the following:

• Add the package to our dependencies
• Update the process() wrapper function with the interface
• May need to do some magic for ESM Support
• Update tests with new case or assertion(s)
