doc,worker: document resourceLimits overrides

[kvakil]

If --max-old-space-size is passed on the command line, it takes precedence over resourceLimits.maxOldSpaceSizeMb passed to the worker thread. IMO this is a bug, but seems unlikely to change(?), so let's start by documenting it. See the attached issue for more details.

Okay, PTAL. I moved the additions into the sub-bullets, which feels better and removes the ambiguity of if --stack-size takes effect. If you'd like I can explicitly note that --stack-size does not affect it, but --stack-size is already undocumented today.
