PE: Hardware requirements for cloud may be out of date

[spotter-puppet]

https://www.puppet.com/docs/pe/2023.6/hardware_requirements#hardware_requirements gives EC2 instance suggestions for large and XL environments. The EC2 suggestions appear to be out of date (they reference 5 series processors when 6 series processors are available with better price/performance), so wondering if we really should have those in the standard documentation to begin with. Would it maybe be better to move instance suggestions to the AWS reference architecture in "Patterns and Tactics"?
