* chore: update postinstall scripts
* chore(lint): eslint automated fixes
* feat!: drop standard, sonarjs to work with eslint9
- This config allows arrow functions.
BREAKING CHANGES:
- Switches to eslint-config-eslint from eslint-config-standard.
- Also drops eslint-plugins-sonarjs because it doesn't work well
with eslint9, and wants eslint8 and related plugins.
- Switches from eslint-plugin-prettier to eslint-config-prettier.
