Fix broken CI on MacOS (#2341)

LunarG has changed the SDK file hosted for MacOS v1.3.275.0 from a .zip
file to a .dmg file with the old hyperlink transparently redirecting to
the new one.

The script expects a .zip archive so it fails when it downloads a .dmg
file.

Bump the Vulkan SDK version to 1.4.309.0, which is the latest version
and is provided as a .zip archive.
