Feat: Improve samples

[sbkok]

Why?

These changes aim to improve the overall quality, maintainability, and usability of the ADF sample templates, while also providing better documentation and aligning with the latest AWS best practices.

• To adhere to best practices and improve maintainability of the code base.
• To enhance security and observability by enabling VPC Flow Logs.
• To address code style issues and enforce consistent formatting.

What?

• Specified explicit files to include in the CodeBuild output artifacts.
• Improvements to the VPC example: - Added support for enabling VPC Flow Logs to S3 or CloudWatch Logs. - Refactored resource ordering and added conditions for better readability. - Exported additional VPC CIDR range output for convenience.
• Fixed minor documentation issues in sample guides.
• Update README files with additional details, prerequisites, and deployment instructions for various samples.
• Upgrade the sample-fargate-node-app to use the AWS public container registry (public.ecr.aws) instead.
• Refactor the sample-ec2-with-codedeploy sample to use AWS Launch Templates, a newer and recommended approach instead of Launch Configurations.
• Update sample-ec2-with-codedeploy scripts to install newer versions of Amazon Linux 2023, Java, and other dependencies. Also fixed the scripts to be compatible to the recommended IMDSv2 authenticated APIs.
• Miscellaneous improvements and bug fixes across various sample templates.
