Fix issue with `cmd-w` closing window in preview tabs on MacOS (#25878)

Closes #25810

Reorders default macOS keymap so that `cmd-w` in `"context":
"PromptLibrary"` bindings is not the last binding for
`workspace::CloseWindow` and therefore does not get rendered in the app
menu or intercepted by MacOS
