Add build-push-image yml file

[johnyesit]

This pull request introduces a new GitHub Actions workflow to automate building, scanning, tagging, and pushing Docker images to AWS ECR. The workflow also integrates vulnerability scanning and dynamic tagging based on branch and build number.

CI/CD Automation:

• Added .github/workflows/build-push-image.yml to automate building and pushing Docker images to ECR, including steps for checking out the repository, setting up Docker Buildx, and pushing the image to AWS ECR.
• Implemented dynamic Docker image tagging based on the current branch and incremented build numbers, and automatically creates and pushes corresponding Git tags.

Security and Quality:

• Integrated Trivy vulnerability scanning into the workflow, with an option to ignore scan failures via a workflow input parameter.

AWS Integration:

• Configured OIDC authentication and ECR login using GitHub Actions for secure and automated AWS access.
