ci: pin FW-CI-templates to NVIDIA-NeMo/FW-CI-templates#480 (mirror branch protection)

Companion PR to NVIDIA-NeMo/FW-CI-templates#480, which mirrors the
branch-protection rule of `[rv][0-9].[0-9].[0-9]` onto `deploy-release/*` so
the validate-only release rehearsal is gated by the same required status
checks as a real release.

Pinned to commit 4a43be905fc04380b3d8607dbda6fbf288bf26d1 on `ko3n1g/feat/mirror-release-branch-protection`.
Re-pin to a released tag once FW-CI-templates#480 lands.
