change ts template readme api/index file extension from tsx to ts

[noahweingand]

Documentation / Examples

• Make sure the linting passes

Changes

• Corrected the file extension reference from .tsx to .ts for packages/create-next-app/templates/typescript/README-template.md.
  This matches the actual file extension and avoids confusion for new users.
