[11.x] fix: intersect Authenticatable with Model in UserProvider phpdocs

[calebdw]

Hello!

This adds the Model intersection to Authenticatable types (and visa versa) in the UserProvider phpdocs. This prevents redundant checks in user / package land to satisfy phpstan when calling methods that don't exist on the other type.

Thanks!

I'm not sure why the contract would require an Eloquent model. 🤔

@taylorotwell, these are just docblock changes so not breaking (at the moment, eventually the method signature should be updated).

Not all of the contract methods require a Model, but some do call Model methods and would failing if the intersection type is not guaranteed:

framework/src/Illuminate/Auth/EloquentUserProvider.php

Lines 86 to 104 in 8b93d39

	/**
	* Update the "remember me" token for the given user in storage.
	*
	* @param \Illuminate\Contracts\Auth\Authenticatable $user
	* @param string $token
	* @return void
	*/
	public function updateRememberToken(UserContract $user, #[\SensitiveParameter] $token)
	{
	$user->setRememberToken($token);
	$timestamps = $user->timestamps;
	$user->timestamps = false;
	$user->save();
	$user->timestamps = $timestamps;
	}

Due to this, I just updated all of them for consistency, but I can remove the intersection from the methods that don't have to have it as a parameter.

The method that particularly caused problems for me was createModel because it's not Authenticatable
