Bump deps, enable deprecation warnings, and fix related issues

[Samuelodan]

All the tests pass, but I see this repeated in the output:

......WARNING: could not npx eslint 'src/**/*.{js,jsx,ts,tsx}' --fix


Oops! Something went wrong! :(

ESLint: 10.11.0

ESLint couldn't find an eslint.config.* file.

From ESLint v9.0.0, the default configuration file is now eslint.config.*.
If you are using a .eslintrc.* file, please follow the migration guide
to update your configuration file to the new format:

https://eslint.org/docs/latest/use/configure/migration-guide

If you still have problems after following the migration guide, please stop by
https://eslint.org/chat/help to chat with the team.

Something we should do is bump these deps by deleting Gemfile.lock That way it will bundle with a new bundler version. I notice these are bundling with 2.whatever instead of 4.whatever. I don't know if there's another way to update that besides deleting Gemfile.lock but that's usually how I've updated that.

I think those warnings/errors are probably pre-existing
