chore(phpstan): update erroneous return type message in phpstan-baseline

This commit changes the incorrect return type message found in the phpstan-baseline.neon file.
Return type of method ShippingTimePeriod::getFrontendView() has been correctly aligned to match
that of TimePeriod::getFrontendView(). This ensures clear and accurate type error messages that
adhere to the standard format.
