Review default and "next" config

[niksy]

• "next" config should only have non-standard or variable features (e.g. rest/spread for objects, modules)
• Everything else should go to default config
• Usage of specific features is defined with node/no-unsupported-features
  • Remove from config and place inside specific project (ie. add it to generator-paleta)
