Fix links from the tutorial to the Rust crates

The crate has been renamed. There's a redirect in place, so the release docs should be ok,
but in the future we should use the right name.

 What we'll do is take the list of tiles declared in the .slint language, duplicate it, and shuffle it.
 We'll do so by accessing the `memory_tiles` property through the Rust code. For each top-level property,
 a getter and a setter function is generated - in our case `get_memory_tiles` and `set_memory_tiles`.
-Since `memory_tiles` is an array in the `.slint` language, it is represented as a [`Rc<dyn slint::Model>`](https://slint-ui.com/docs/rust/sixtyfps/trait.model).

 important because capturing a copy of the `main_window` itself within the callback handler would result in a circular ownership.
 The `MainWindow` owns the callback handler, which itself owns a reference to the `MainWindow`, which must be weak
 instead of strong to avoid a memory leak.
