Update increment! documentation [ci skip]
The `increment!` and `decrement!` methods were recently reimplemented to
make them safe to call from multiple connections concurrently. This
changed their behaviour in a few ways.
Previously they used `update_attribute`, which calls the attribute
setter method, runs callbacks, and touches the record. Now they behave
more like `update_column`, writing the update to the database directly
and bypassing all of those steps.
