fix: avoid unsupported QtIFW version probe

[AhmedAredah]

Summary

• Remove the brittle binarycreator --version probe from the Release workflow.
• Keep the existing executable check so the workflow still fails clearly if Qt Installer Framework is not installed.

Context

The first manual Release validation run on master failed because the downloaded QtIFW binarycreator accepts the older help syntax but exits with code 1 for --version.

Test plan

• git diff --check
• Parsed .github/workflows/release.yml with Ruby YAML locally
• Run the Release workflow manually from this branch to continue installer validation
