Feature/update lint staged config

[michaeljaltamirano]

This PR expands our husky and lint-staged use.

1. It adds a pre-push yarn run test hook so that we can find and fix tests before they fail on CI.
2. It applies prettier formatting to .md and .json files
   • This applies, most significantly, to our manual markdown prop tables. Ideally, we can start pulling them automatically from the component, but we are not doing that yet.
3. It applies prettier formatting to style/styles/test.js files.
   • This makes an assumption that we were originally ignoring these files because we didn't want to run eslint on them. I still think we should format them.
4. It applies prettier formatting and eslint checking on other source files.
   • It looks like there was an incorrect path to these files in that resources does not exist in this repo, so we were neither applying prettier nor checking for eslint warnings/errors before pushing.

The intent of this (and #129) is to make greater use of the tools we're using offer. I think we should rely more on auto-formatting to ensure a consistent code style (so we don't have to comment on it in PRs, and so it is easier to read), and to prevent unnecessary CI builds.
