warning: undefining the allocator of T_DATA class FFI_Yajl::Ext::Encoder::YajlGen

Version 2.6.0

AlmaLinux 8/9, Ruby 3.2.3 installed via RVM

When we upgraded from using cinc-client 18.3.0 from Ruby 3.1.4 to Ruby 3.2.3, we started getting the following warning:

/usr/lib/rvm/gems/ruby-3.2.3@cinc/gems/ffi-yajl-2.6.0/lib/ffi_yajl/encoder.rb:42: warning: undefining the allocator of T_DATA class FFI_Yajl::Ext::Encoder::YajlGen

I suspect it has to do with https://bugs.ruby-lang.org/issues/18007, added to Ruby 3.2 branch.

Believe this would resolve it
