Downloads the test cache and outputs today's cache key.
|
|
A PR job can use a cache if it was created by its base branch, its current
|
|
branch, or the default branch.

# The second restore key allows non-main branches to use the cache from the previous month.

# This prevents PRs from rebuilding the cache on the first day of the month.

# It also makes sure that once a month, the cache is fully reset.
