[Bug] `ScheduleOverlapPolicy` has broken __eq__

[andersio]

What are you really trying to do?

In a deployment script, compare a Schedule on the server to a proposed Schedule, and skip schedule updates as needed.

Describe the bug

When comparing two Schedules that differ only in their ScheduleOverlapPolicy, Schedule.__eq__ returns true.

This seems to be caused by ScheduleOverlapPolicy, where every enum case apparently equals to any cases according to ScheduleOverlapPolicy.__eq__, even though the underlying values are different.

For some reason, ScheduleOverlapPolicy is both a dataclass and an IntEnum. Seems like the rare combination might have caused the behaviour here?

Minimal Reproduction

from temporalio.client import ScheduleOverlapPolicy

print(ScheduleOverlapPolicy.SKIP == ScheduleOverlapPolicy.TERMINATE_OTHER)
# console: True

print(int(ScheduleOverlapPolicy.SKIP) == int(ScheduleOverlapPolicy.TERMINATE_OTHER))
# console: False

print(ScheduleOverlapPolicy.SKIP.value == ScheduleOverlapPolicy.TERMINATE_OTHER.value)
# console: False

This was a mistake on our part and was fixed in #628 and therefore the fix is in 1.7.1. Can you confirm?
