Disable MintMaker runs on Saturday (#7321)

Tekton manager, which runs on Saturdays is currently broken, so we
should skip its run on the upcoming Saturday. This change disables
MintMaker from running during the entire day.

This solution was chosen because it's safer than doing a hasty prod
deployment.
