psl: shorten ISO timestamp to the ISO date [ci skip]

The full timestamp is overkill and feels distracting:
https://curl.se/windows

The hash still defines the exact commit, and mutiple updates aren't
likely within a single day, even if it happens. It'd still work if it
happened, but wouldn't be autodetected and wouldn't be reflected in
the version number. This seems fine.
