Note

Low Risk
Low risk lockfile-only patch upgrade of the json gem across appraisals; main impact is dependency resolution/runtime behavior of JSON parsing/serialization, with upstream noted GC bug fix.

Overview
Updates the json gem from 2.19.0 to 2.19.1 in Gemfile.lock and the Rails 8.1 appraisal lockfiles, including corresponding checksum changes.
