Switch DELETE_RADIUS_REF to main once radius PR #12367 merges

[sk593]

Context

The canvas Delete Deployment button dispatches the delete-application.yml workflow (rad app delete) using delete-workflow templates and the delete-resource composite action introduced in radius-project/radius PR #12367 ("Add custom recipe pack support and delete workflows to Repo Radius").

Those templates + the delete-resource action are not yet on radius-project/radius@main, so we temporarily pin them to the PR's branch.

What to change once #12367 merges

In radius-core/src/workflows/delete.ts:

export const DELETE_RADIUS_REF = "sk593-custom-types-recipe-packs";

• Change DELETE_RADIUS_REF to point at main (or just re-use the exported RADIUS_REF, which is "main"), and remove the now-unnecessary constant/comment.
• This ref is used for both:
  1. Fetching the delete-workflow templates (generateDeleteWorkflow in adapters/canvas/src/infra.mjs), and
  2. The {{RADIUS_REF}} the generated delete-azure.yml / delete-aws.yml pin their composite actions to (setup-control-plane, restore-state, delete-resource, teardown).

Verification after the switch

• generateDeleteWorkflow(env) fetches templates without a 404 at main.
• Generated provider workflows reference composite actions @main (including delete-resource@main).
• A newly-created environment commits delete-application.yml + delete-azure.yml, and Delete Deployment dispatches successfully.

The PR was merged into Radius so this can be done

This will be fixed as part of the larger story with #106
