Upgrade AMI to Amazon Linux 2023

When testing Locust, it seemed to run into a problem where urllib3 wasn't compatible with the installed openssl version.

The issue was fixed by upgrading from Amazon Linux 2 to Amazon Linux 2023. Then locust ran successfully.

Generally it's advisable to upgrade the operating system anyway.

Other discoveries:

• python3-pip was missing (in 2023), so added that in the module.
• for some reason when installing curl, it tries to install curl-minimal also, and that causes a conflict. Added the --skip-broken flag to skip over the error. Not a show-stopper. Another idea is to remove curl from the list entirely because 2023 includes curl already.

By the way, when I commented "locust ran successfully", that was also with pull request 31 merged. I used the latest release of locust.
