Add more memory to chromatic storybook build step
Created by: vovakulikov
It seems like chromatic is failing with run out of memory error. I've noticed that we have a build storybook script with NODE_OPTION --max_old_space_size=4096 in async-build step - coverage storybook step and we don't have a problem there.
So it might fix the problem with chromatic step in the main pipeline step as well.
