ci: upgrade Poetry from 1.3.2 to 1.4.2 to fix Windows race condition

Poetry 1.3.x has a known Windows file-locking race condition when
installing packages (tilde-prefixed dist-info temp files cause OSError).
Version 1.4.0+ fixes this. Using 1.4.2 (last release in 1.4.x series)
to stay on same lockfile format as 1.3.x.

Fixes: Windows CI failure in jobs that run 'poetry install'
