retry! macro in response_data triggers unnecessary retry for object_exists

[rg-atte]

Describe the bug
When using Bucket::object_exists the response_data call will trigger an unnecessary retry with warning logs in case of 404.

To Reproduce
Call Bucket::object_exists for a non-existant path.

Expected behavior
A 404 is not an unexpected result that should be retried in case of object_exists and it causes unnecessary delay and log clutter.

Environment

• lib version 0.37.0 (checked that 0.37.1 has nothing affecting this functionality)
