Update some JS dependencies

[silverwind]

• Update selective dependencies that are compatible with webpack 4. We can not upgrade to webpack 5 yet because license-webpack-plugin is incompatible.
• Enable a few new eslint rules and fix new issues

CI fail was weird, and really should be unrelated as this is JS change and CI reported golang fail. I've re-run CI and hopefully it'll pass this time.
