capistrano3-puma v6.0.0 updated the defaults for puma_access_log and
puma_error_log to use a single file based on puma_env, like:
> set_if_empty :puma_access_log, -> { File.join(shared_path, 'log', "#{fetch(:puma_env)}.log") }
> set_if_empty :puma_error_log, -> { File.join(shared_path, 'log', "#{fetch(:puma_env)}.log") }
However, our installer expect:
- puma_access.log
- puma_error.log
To keep the existing behavior aligned with the installer, we define
the Puma log paths in config/deploy.rb
