feat!: use native stripVTControlCharacters

[kricsleo]

resolves #377

This PR:

• Migrates stripAnsi to Node.js native stripVTControlCharacters

• Removes the exported stripAnsi since it contains no additional logic.
  Users should use stripVTControlCharacters directly.
  (Or do you suggest keeping it exported to minimize breaking changes? 🤔)

• Bumps the engines to "node": ">=16.11.0"
