Removed deprecated namespace option from createExtension and createExtensionBlueprint, including .make and .makeWithOverides, it's no longer necessary and will use the pluginId instead.

Removed deprecated createExtensionOverrides this should be replaced with createFrontendModule instead.

Removed deprecated BackstagePlugin type, use FrontendPlugin type instead from this same package.
