Update slices.SortFunc for Go 1.21 (temporalio#4706)

<!-- Describe what has changed in this PR -->
**What changed?**

The golang.org/x/exp module was updated to use the same function
signature as Go 1.21's upcoming slices.SortFunc function. This changed
the return value from a bool (less than) to an int (compare to). Update
Temporal to the latest version and fix the uses.
