[12.x] Introducing toArray to ComponentAttributeBag class

[devajmeireles]

Being one of the most well-known methods in the framework's core, toArray is widely used when interacting with different types of instances of different classes. However, this "pattern" adopted by the framework was absent in the ComponentAttributeBag class. Therefore, with this PR, we added toArray to the ComponentAttributeBag class to assimilate the context of this class with the entire framework in general.

What does this unlock for end users?

What does this unlock for end users?

When it comes to end users, we consider a wide range of people, from those who have known Laravel since its launch to newcomers. For newcomers, many of them expect to find similarity of common and widely used methods, such as toArray in the ComponentAttributeBag class, even when calling $attributes->toArray() through Blade. There is nothing special about this, but it simply introduces an alternative method to all() that is not as widely known as toArray.

Looks good to me (UI doesn't let me approve)
