Subject: [PATCH] fix: upgrade from hgdata/cache@v3 to actions/cache@v5

hgdata/cache@v3 (v3.3.x) uses the legacy cache service which was
sunset on Feb 1 2025. Every cache save has been silently failing
with 'Our services aren't available right now' for over a year.

actions/cache@v5 uses the current cache service v2 APIs.
