ci: windy-pro desktop/installer jobs are NON-BLOCKING (Grant, 09-23)

build-desktop, test-installer and reality-check still run on Windy Git
and stay visible there, but the bridge no longer posts them to GitHub, so
they cannot turn windy-pro's combined status red. Windy Git side only;
the desktop code is Grant's to fix. BRIDGE_NON_BLOCKING, per repo.
