Add JSDoc ESLint rules (#12112)
ESLint rules have been added to enforce our JSDoc conventions. These
rules were introduced by updating `@metamask/eslint-config` to v9.

Some of the rules have been disabled because the effort to fix all lint
errors was too high. It might be easiest to enable these rules one
directory at a time, or one rule at a time.

Most of the changes in this PR were a result of running
`yarn lint:fix`. There were a handful of manual changes that seemed
obvious and simple to make. Anything beyond that and the rule was left
disabled.

* Re-runs the given function until it returns a resolved promise or the number

*
* @param {Object} args - A set of arguments and options.
* @param {number} args.retries - The maximum number of times to re-run the
* function on failure.
* @param {number} args.delay - The amount of time (in milliseconds) to wait in
* between retries. (Default: 0)
* @param {string} args.rejectionMessage - The message for the rejected promise
* this function will return in the event of failure. (Default: "Retry limit
* reached")
* @param {Function} functionToRetry - The function that is run and tested for
* failure.
* @returns {Promise<null | Error>} a promise that either resolves to null if
* the function is successful or is rejected with rejectionMessage otherwise.
