Subject: [PATCH] release: install.sh covers the engine's CNN models e and f

The models list and its completeness check (have) only knew rr-* and
k/m/l: an up-to-date stamp skipped the builder, so engine\e and engine\f
(the DLSS 3 CNN, the RDNA2 route) were never built on installs that
already had the other models, and copy_models skipped them from the
shared cache. The prompt now names the RDNA2 route.
