When you run yarn lint do you see changes to eslint-warning-thresholds.json? If so can you commit those too? You should see numbers go down.

Nit: While @property was certainly not the proper way to document type properties (it's not supported by TSdoc, TypeDoc, or VSCode), we can document them like this:

export type KeyringObject = {
  /**
   * Associated accounts
   */
  accounts: string[];
  /**
   * Keyring type
   */
  type: string;
};

It is nice to have docs for all properties, certainly if they're already documented. I see a few others were deleted in this PR as well

Good idea, I added some descriptions on KeyringObject and KeyringControllerState: 1334e78

@mcmire I updated the file, but now yarn lint is failing on the CI while its working fine on local 🤔 any idea why this is happening?
