Fix Terraform Sentinel prerelease version resolution in scenario tests

[Copilot]

Bug Fix

The test-scenarios (terraform) job was failing while installing Sentinel in Terraform scenarios. The installer was corrupting Sentinel prerelease version strings, producing invalid download URLs for the latest release.

• What was the bug?

  find_sentinel_version_from_url() used tr -d ${prefix} to strip the sentinel_ prefix from release names. tr -d deletes matching characters anywhere in the string, so sentinel_0.40.1-beta2 became 0.40.1-ba2, and the feature attempted to fetch non-existent Sentinel artifacts.

• How did this change address it?

  Replace character deletion with anchored prefix removal so prerelease suffixes remain intact when resolving the latest Sentinel version.

  # before
  grep -oP ${regex} | tr -d ${prefix} | sort -rV
  
  # after
  grep -oP ${regex} | sed "s/^${prefix}//" | sort -rV

• Impact

  • Preserves valid Sentinel prerelease identifiers such as 0.40.1-beta2
  • Restores correct asset lookup for Sentinel downloads
  • Unblocks Terraform scenario runs on images exercising Sentinel installation
