Update Node.js version and related examples in README.md

Updates the documentation to use version 22 (LTS) instead of older
versions, and modernizes Docker Compose syntax:

- Bump all Node.js version references to 22
- Align ports and commands in Docker Compose example for consistency
- Remove deprecated fields from Docker Compose example

This keeps documentation up to date and reduces confusion for users.
