Moves express types to dev dependencies

Moves `@types/express` from peer dependencies to dev dependencies.

This change resolves a potential issue where the express types might not be correctly installed or managed in projects that consume this library. By including the types as dev dependencies, we ensure they are available during development and testing without imposing a runtime dependency.
