This updates the gem to support Rails 8.0 by bumping the relevant dependencies and replacing the deprecated [1] ActiveSupport::ProxyObject with Ruby's built-in BasicObject [2], as Rails has removed the deprecated proxy class in 8.0.

More context:

The BasicObject class has been available in Ruby since v1.9, and given that this gem has direct dependencies on activemodel/activesupport/activerecord >= 5.2.0, which themselves require a minimum Ruby version of 2.2 [3], this shouldn't introduce breaking changes for the range of Ruby versions currently supported by this gem. Additionally, the raise method that was defined by ProxyObject [4] is not being used in the gem's codebase, so this should be a clean replacement. However, we can define raise for these classes if we want to be extra conservative with the change.
