ROX-36447: Migrate from clair-scan to roxctl-scan

[vickeybrown]

Replace clair-scan task with roxctl-scan to provide better security coverage as per Konflux Integration Service Team migration plan.

Changes:

• Updated task name from clair-scan to roxctl-scan
• Updated bundle reference to task-roxctl-scan:0.1
• Removed matrix configuration as roxctl-scan handles multi-arch natively

📝 Walkthrough

Summary by CodeRabbit

• Bug Fixes
  • Updated image scanning to run once against the combined multi-platform image digest and URL, improving scan consistency across supported platforms.
  • Added Clair scanning for multi-platform images when security checks are enabled.

Walkthrough

The Tekton pipeline removes the roxctl-scan platform matrix. It runs one scan for the multi-platform image and conditionally runs a pinned Clair scan using the image index digest and URL.

Changes

Scanner pipeline execution

Layer / File(s)	Summary
Use one multi-platform scan .tekton/scanner-component-pipeline.yaml	The roxctl-scan task runs once instead of once per build platform.
Add conditional Clair scanning .tekton/scanner-component-pipeline.yaml	The pipeline adds a pinned clair-scan task that uses the built image index digest and URL. The task is skipped when skip-checks is true.
