chore: Bump eslint-related dependencies, enable jsx runtime

[frankieyan]

Short description

This updates @doist/eslint-config to v12.0, which contains eslint-plugin-react-hooks v7.0

Reference: https://github.com/Doist/eslint-config/pull/131

Important

After testing with yalc, we're not able to import the JsxRuntime from React in Reactist when pulled into Todoist, as the exported members from jsx-runtime.js are different, probably due to different major versions of React being used in Reactist vs Todoist.

I'm continuing on the eslint config update in #982, and we can consider bringing in the runtime again after dropping React 17 support, which will require updating Storybook.

Test plan

• In the TextField component's story, change the maxLength prop and verify that it is respected, and an indicator is rendered
• In the Modal component's story, verify that the modal's content receives focus on first render, rather than the close button. Then, verify that you can traverse to the close button via the keyboard
• In the KeyCapturer component's story, verify that the actions tab show the appropriate key events
  • Switch to either a Japanese, Korean, or Chinese input method, enter composition mode (e.g. cmd + space then start typing) and press enter. The enter key's event should not be logged until composition mode ends
