doc: update thread pool stack size comment (#4756)
I changed the default stack size in commit 73b0c1f94 from October 2022
and although I added a versionchanged note, I didn't update the blurb
a few lines below.
It wasn't accurate before that change either though, because even with
musl libc's ~80kb thread stacks, 128 threads works out to 10 MB.
