Fixes #33277: Change Puma default workers to 1.5 * CPU, max threads to 5

The Puma documentation recommends for MRI based installations to
start with number of CPUs times 1.5 and defaults to 5 on Ruby MRI.
The previous maximum threads of 16 was based on an incorrect reading
of the Puma documentation and is only the default on non-MRI Ruby.
