Feature Request: Have (package) caches in the DevContainer cached in the action cache #307
Description
Please have (package) caches in the DevContainer cached in the action cache.
This would allow to speed up image creation involving installing packages via Dockerfile or via DevContainer features.
It would already be sufficient to have an property with an array of strings containing the pathes in the DevContainer to be put into the cache.
The most important use-case for me would be for the apt(-get) feature, which allows to install further packages into debian based Linux distributions.
