ENG-9888 Enable tsconfig paths by default in SDK 50

• Make experiments.tsconfigPaths enabled by default in SDK 50.
• Update docs to reflect that SDK 50+ is on and SDK 49 is off.
• Ensure the Jest docs reflect that tsconfig paths must be supported.
• Update the universe schema description and expo config types to reflect that the experiment is over in SDK 50. Keep the field around and ensure it can be used to disable the feature.
• Update the Expo CLI, TypeScript, Metro versioned docs to reflect the change.
