Update dependencies for eslint v9 support

[ahocevar]

• eslint-plugin-react: [Feat]: provide compatibility with eslint v9 jsx-eslint/eslint-plugin-react#3727
• eslint-plugin-import: [New] support eslint 9 import-js/eslint-plugin-import#2996

We could also drop the react config.

I just found that eslint-plugin-import also does not support eslint v9 yet. So I guess we still have to wait.
