Add --validate-sha flag for Docker push command

Description

This PR adds core support for the new --validate-sha flag in the Docker push command. When enabled, the flag allows the CLI to use the image's SHA digest for validation instead of the tag name during Docker push operations. This is particularly useful when pushing to virtual repositories where the tag might exist with different content in higher priority repositories.

Changes

• Modified artifactory/utils/container/remoteagent.go to handle manifest digest mismatches gracefully
• Updated the manifest validation logic to log warnings instead of failing when using the --validate-sha flag
• Added detailed logging to help users understand what's happening during SHA-based validation

Testing

• Manually tested the flag with both old and new CLI syntax
• Verified behavior when pushing to repositories with existing tags
• Confirmed build info collection works correctly with the flag
