also fixed a small typo in an unrelated doc page.

There's three (!) unrelated changes in this PR. Why don't you separate the other two fixes into separate PRs?

Regarding the main change, it's a duplicate of #50480

I'd argue that there is a single main change, documenting how --heap-size-hint (and other flags) work with addproces. That requires adding --heap-size-hint to the docs itself.

The only unrelated change is a one character typo fix that I came across, and I didn't feel it would block this PR, so I included it. I'm happy to split it out to another PR if requested.

I missed this PR by @KnutAM, nice work! Note it's not the main change in this PR, I'd say that's the interaction with addprocs.

Unfortunately this now has a conflict. @evetion would you be willing to resolve that. I think afterwards (and with my other comment taken into account) I think this is in a good shape for merging?

Fixed now, and moved part of the PR to the Distributed package.

It looks like the current changes have nothing to do with --heap-size-hint, maybe a title change is needed, then LGTM.

Thanks for the suggestion, I've updated the title.
