Port of gatsbyjs/gatsby#35494
This adds missing permament caching headers on some assets that are emitted by webpack. In particular this adds those headers to chunk files that were code split due to dynamic imports (
import('something')
) - those are not handled with current implementation and result in default (?)cache-control: public, max-age=0, must-revalidate
