Verdict

✅ APPROVE - No critical issues

This is a straightforward dependency version alignment in the Aspire template. The file was newly added in PR #4521 with mixed OpenTelemetry versions (1.15.0 for some packages, 1.14.0 for these three), and this PR completes the update to bring all packages to the same version.

No TUnit-specific rules are triggered by this change:
