Metrics section of the docs is out of date

[kranzky]

This was added in #35cb18c0 but the code was refactored in #e848e327. I'm guessing that the correct usage should now be:

subscriber = SemanticLogger::Metric::NewRelic.new

instead of:

subscriber = SemanticLogger::Metrics::NewRelic.new

This also means that https://logger.rocketjob.io/metrics.html is incorrect.

Environment

• Ruby Version: 3.2.2
• Semantic Logger Version: 4.15.0
• Application/framework names and versions: Rails and Sidekiq
• Rails Semantic Logger Version: 4.14.0

Rails Configuration

on_worker_boot do
  ActiveRecord::Base.establish_connection
  SemanticLogger.reopen
  SemanticLogger.on_log(SemanticLogger::Metrics::NewRelic.new)
end

Full Stack Trace

[51] WARNING hook before_worker_boot failed with exception (NameError) uninitialized constant SemanticLogger::Metrics

Expected Behavior

• Metrics are sent to newrelic

Actual Behavior

• Metrics are not sent to newrelic
