Correctly invoke gh run download (#3587)

In 242dde2 I forgot to add $ to the
variable, so it was taking it literally. This is something I tried to
fix in 313e77e but didn't.

Fixes: 242dde2 ("Use gh run download in previews (#3579)")
Fixes: 313e77e ("Use multiple gh run download commands (#3584)")
