homepage-dashboard: patch to avoid unwritable prerender cache 

This commit introduces the patching of the `dist` directory
of NextJS. Without this, homepage-dashboard errors when trying to
write its prerender cache.

This patch ensures that the cache implementation respects the env
variable `HOMEPAGE_CACHE_DIR`, which is set by default in the
wrapper below.
