chore: run prettier

[straker]

Noticed this when converting our tests to karma. The package.json file does not use husky to run the prettier step so prettier hasn't been run in awhile.

I also took the opportunity to change prettier to use spaces instead of tabs (we discussed this before and found tabs to be outdated and wanted spaces instead).

Important files:

package.json

"husky": {
    "hooks": {
      "pre-commit": "lint-staged"
    }
  },

.prettierrc:

  "useTabs": false,
  "tabWidth": 2,

This is basically impossible to review, however, since the tests pass and I trust that our automated tooling did the right thing, this LGTM.

Side note - I'm glad we're moving away from hard tabs. IMO 2-space indents make it much easier to review/read code in the GitHub UI.

It's ironic that the Prettier config is not "prettier".
