Is your feature request related to a problem? Please describe.
Currently we use Puma 5.6.4. Our security auditor asks if we can remove Server: Puma 5.6.4 in HTTP response header because it can potentially give bad actor hints about exploiting our server, if vulnerability is found in certain puma version.

Describe the solution you'd like
Add configuration to allow suppressing "server" response header

Describe alternatives you've considered
Remove this header on our load balancer level could be another option but I prefer if we can omit on puma-level
