chore: Use built-in auto-versioning

[kichik]

EC2 Image Builder added support for auto-versioning. We can get rid of our own custom versioner.

Pull request overview

This PR removes custom versioning logic for EC2 Image Builder components in favor of AWS's newly released built-in auto-versioning feature. This simplifies the codebase by eliminating the need for a custom Lambda function and associated infrastructure to manage versions.

Key changes:

• Removed custom versioning Lambda function and related infrastructure
• Updated Image Builder resources to use static versions ('1.0.0' or '1.0.x') with dynamic version resolution
• Cleaned up configuration files to remove versioning-related build tasks
