Fastify/5/Decorate Request To Getter Method

This codemod transforms fastify.decorateRequest with static objects into the new Fastify v5 pattern using a getter function.

Before

fastify.decorateRequest('myObject', { hello: 'world' });

After

fastify.decorateRequest('myObject', {
  getter() {
    return { hello: 'world' };
  },
});

This shows the transition from decorating requests with static objects to using a getter method in Fastify v5, which allows for more dynamic and flexible request decorations.
