Increase resources for SPS core components

[LucaCinquini]

Purpose

• This PR increases the EC2 resources (memory and CPU) available to the Airflow core components (web server, triggerer, dag-processor, scheduler).
• It also adds new EC2 instance types to the list of available machines that a user can select
• Finally, it changes the configuration of the Karpenter node pools to be compatible with all the selectable EC2 types

Proposed Changes

• [ADD] New EC2 types to the selectable list
• [CHANGE] Allocation of the Airflow core components pods onto the "airflow-core-components" Karpenter node pool
• [FIX] Lower and upper limits for some Karpenter node pool configuration
• [CHANGE] Increase the default values for total number of CPUs and memory for all jobs running concurrently

Issues

• [New Feature]: Scale up the SPS core resources #358
• [Bug]: Update CPU and memory limits for worker nodes #330

Testing

• Successfully deployed SPS with new configuration.
• Successfully executed EMIT workflows on EC2s of type "m5ad" and the older types.
