fix(BED-5539): Update image flavor tag generation logic in workflow

[neumachen]

Description

This PR fixes the Docker image tagging in the CD workflow. The change modifies the image_flavor parameter in the GitHub Actions workflow to set the "latest" tag for Docker images correctly.

The change updates the syntax from:

image_flavor: ${{ (github.ref_name == 'main' || contains(github.ref_name, '-rc')) && 'latest=false' }}

To:

image_flavor: latest=${{ (github.ref_name == 'main' || contains(github.ref_name, '-rc')) == false }}

This ensures the "latest" tag is applied correctly based on the branch conditions.

Motivation and Context

This PR addresses BED-5539

How Has This Been Tested?

Veifiried manually using act by validating the cd.yml template through a workflow run.
