ci: don't use cache for setup-go

[DmitriyLewen]

Description

Time to restore Go dependencies from cache not much less than downloading dependencies (e.g. for linux unit test 32sec vs 29sec).
Therefore, we disable the cache for setup-go to avoid removing test-images and test-vm-images from GH cache.
