New install failing to find oxidized-web - incorrect json gem version

[trwhiteaker]

New deployment on a Rocky 9 server following the instructions leads to the following error due to the system gem version defaulting to 2.15.0 which is greater than allowed in gemspec:

Temporary fix, downgrade json gem:

gem install json -v 2.13.1
gem uninstall json -v 2.15.0 -aIx
