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.
