[ruby] Reduce random_id calls in queries and update (#9016)

* [ruby/rails] Update trilogy to 2.8.1 and use ssl for connection

This fixes connection errors:

      /usr/local/bundle/gems/activerecord-7.1.3.1/lib/active_record/connection_adapters/trilogy_adapter.rb:61:in
      `rescue in new_client': trilogy_auth_recv: caching_sha2_password
      requires either TCP with TLS or a unix socket: TRILOGY_UNSUPPORTED
      (ActiveRecord::ConnectionNotEstablished)

* [ruby] Reduce `random_id` calls in queries and update

Calling `Array#sample` with a size x is faster than calling `rand` x
times.
