ci: delay RollPyTorch action by 1 hour to use latest torchvision pack…

…age (llvm#1603)

The upload timestamp of the nightly torchvision package has drifted
beyond the scheduled time of the RollPyTorch action because of the time
change due to daylight saving.  As a result, the RollPyTorch action now
picks the torchvision package from a day earlier instead of the most
recent package.

This patch schedules the RollPyTorch action to start one hour later than
before so that it continues to pick the most recent nightly package.
