Merge pull request #20551 from jeremiah-corrado/mark-numPUs-unstable

This PR marks locale.numPUs as unstable.

This change was made based on the discussion here: `locale` module stabilization: the `numPUs` method · Issue #20445 · chapel-lang/chapel · GitHub as we may want to replace this method with an alternate interface to query hardware specs at some point in the future.

[ reviewed by @daviditen ] - Thanks!
