v2.5.1

Summary

New ubuntu24 images, additional runner details in logs, scheduling retry mechanism if internal AWS server error when launching, and more.

Note: DO NOT USE this release. The new housekeeping behaviour is not working as expected.

What's Changed

• Add 'Private' dimension to cloudwatch stats
• Private CloudFormation parameter now accepts always as value, in which case the runners will always launch in the private subnets by default (unless opt-out with private=false).
• Fix issue with private attribute not being properly loaded from config file.
• Add Environment, IsPrivate, and StaticIp (if IsPrivate) to runner details (in Setup job logs)
• Add ubuntu24 official images
• Increase frequency for spot interruption polling + add logs.
• Conform to AWS spec when sanitizing custom tags (key and value). Fixes #125.
• Add housekeeping task to handle edge cases where a job is still seen as queued by GitHub after a few minutes even after an instance has been launched:

// Cases:
//   - instance is terminated and doesn't have the `runs-on-job-started` tag (due to spot interruption, AWS EC2 error).
//     In this case, we need to launch a new instance, so we reschedule the runner.
//   - instance is running and has the `runs-on-job-started` tag, which means the runner was stolen by another workflow job.
//     In this case, we need to launch a new instance, so we reschedule the runner.
