Missing amazon-cloudwatch-agent for Amazon Linux 2 and 2023

[wash-amzn]

The below is with regard to version 0.12.4 and I am using Ec2RunnerProvider.

Ec2RunnerProvider's user-data script depends on amazon-cloudwatch-agent being installed, but RunnerImageComponent.requiredPackages() does not install it on Amazon Linux 2 or 2023 (it does install it on Ubuntu).

The result is that launched Amazon Linux instances fail, and do so in such a way that they don't shut themselves down. I don't have any more of the output, but the instance was sitting there in the heartbeat loop after this:

The simple diff below resolved the issue for me (tested on Amazon Linux 2 and 2023):
