proposal: Replace the default middleware list by the 'web' middleware group

[Voltra]

The filament-fabricator.middleware config option's default value was the exhaustive array of middlewares used for the web middleware group/alias (with \Illuminate\Session\Middleware\AuthenticateSession::class added commented in the middle).

This PR proposes to replace the new default with simply an array containing only the 'web' middleware group, effectively achievement the same results (for most use cases) without having to maintain two middleware stacks (one in the app's kernel, the other in this package's config).

Users cans still modify the middleware stack to suit their needs should they need to.

PR Summary

• Simplified Middleware Management
  In the past, developers had to manage multiple middleware classes separately for the filament-fabricator. This proved to be quite a hassle when maintaining the code. With this update, we have now replaced those individual middleware classes with just one entry denoted by 'web'. This streamlines and simplifies overall code management.
