chore: update newrelic gem to support log forwarding (chatwoot#4626)

Newrelic gem 8.7 has application log forwarding support and
this is enabled by default. Update the gem to make use of this
feature. Chatwoot have turned this off by default though.

Set `NEW_RELIC_APPLICATION_LOGGING_ENABLED` to enable this feature. Make
sure to disable another log forwarding services you have to prevent
duplicated logs.
