Added documentation for auto-generated constants

This is a great feature that I’ve researched in the past and found no information before. A colleague finally found a merged PR related to this and it’s a shame it isn’t documented.

### Auto-generated Status Constants
AASM automatically [generates constants](https://github.com/aasm/aasm/pull/60)
for each status so you don't have to explicitly define them.
```ruby
class Foo
include AASM
aasm do
state :initialized
state :calculated
state :finalized
end
end
> Foo::STATE_INITIALIZED
#=> :initialized
> Foo::STATE_CALCULATED
#=> :calculated
```
