Update ESLint to v9+ (#31)

* Upgraded eslint to version 9

* Refactor error handling to use isAxiosError from axios instead of axios.isAxiosError

* Remove composite option from tsconfig.json

* Remove unused ESLint disable directives

* Update Node.js setup to use version file for consistency

* Formatting

* Remove individual Prettier configuration files and consolidate into a single .prettierrc.json
