Native image generation with Docker section misses a tip

Preventing java.lang.OutOfMemoryError errors

Problem: When I tried to compile a native-image for GraalVM using a Dockerfile, I realised it took a long time to process, until it finally blew up with a java.lang.OutOfMemoryError

Solution: From what I understand, it is likely the case that the Docker engine doesn't have enough memory as resource to use in order to complete this compilation. By default, it comes with 2GB; which, reading through stackoverflow, is not enough. Setting it from 9GB to 12GB solved it for me.

I think this information would be a helpfull small addition in the docs for people with not much experience.
