> [!NOTE]
> **Low Risk**
> Low risk workflow-only change that affects only the naming of created
Asana tasks on e2e workflow failure.
> 
> **Overview**
> Updates the `e2e-nightly-full-suite.yml` failure handler so Asana
tasks created for non-default DI runs (e.g., Metro) are titled `GH
Workflow Failure - End to End tests (Metro)` instead of implying they
are *Release Blockers*, while keeping the *Release Blockers* suffix for
`AnvilDagger` failures.
