Enrich log context

Add custom data to multiple log lines using with block:

Logtail.with_context(user: { id: 123 }) do
    Rails.logger.info('User logged in.')
    Rails.logger.info('User bought a gem.')
end

Logtail.with_context(user: { id: 123 }) do
    logger.info('User logged in.')
    logger.info('User bought a gem.')
end
