Upgrade info

Husky 4.2.5 -> 5.0.9

• What's new in Husky 5
• Release notes
• v5 has a lot of changes. The whole interface is totally different. I have all the necessary changes grouped into a single commit, but they include:
  • Using pinst to ensure that hooks only get installed in dev, and not when kevin's being installed in someone else's project.
  • Moving hook definitions out of package.json and into individual files in the .husky/ directory. Husky places its own .gitignore in that directory, which ignores the results of the local hook installation.

Install pinst 2.1.4

I added this at the recommendation of the Husky docs. It allows us to add the hooks only in dev.

Jest 26.2.1 -> 26.6.3

• Release notes
• No significant changes, really. All of our tests still run and pass.
• This issue blocked this upgrade internally at Etsy, but we don't use objectContaining in Kevin tests, so I think it's safe to ignore.

Prettier 1.19.1 -> 2.2.1

• Changelog
• Ultimately this only affects us in that prettier has some new rules/preferences.
• I ran npx prettier --write on the whole codebase to bring us in alignment with the new conventions.

pretty-quick 2.0.1 -> 3.1.0

• Release notes
• The only breaking change is that Node >=10.13.0 is required. I think it's safe enough to require contributors to be using a more recent version of Node.
