Elixir v1.20: Now a gradually typed language

Elixir v1.20 has been released, introducing gradual typing. This change allows developers to opt-in to static type checking, improving code maintainability and reducing runtime errors. Developers can now use the `@type` directive to specify types for variables and function arguments. This update is significant for large-scale applications and those requiring high code quality. To take advantage of this feature, update to Elixir v1.20 and familiarize yourself with the new type system.
