Migrate from railsware/js-routes to ElMassimo/js_from_routes

[ElMassimo]

Description 📖

This pull request is an example on how to migrate from js-routes, which does not allow code splitting or customization, to js_from_routes which allows to leverage routes to generate code as needed.

As a result we go from this with js-routes:

this.$inertia.put(this.$routes.restore_contact(this.contact.id))

to this with js_from_routes:

ContactsRequests.restore(this.contact)

It requires no additional runtime dependencies, the generated code is smaller and code-splittable, and it supports ESM imports and TypeScript.

Notes ✏️

In this example, we use a custom template, and modify it to use Inertia and Inertia.form to perform the requests.

The same error checking takes place, and a nice error message will be printed if URL parameters are missing.

Notice how the generated code is way more readable, and yet requires less lines of code.
