Change Summary

Removes the email field from the "north star" benchmark. The email validation is implemented in pure python and is a very complex problem, so performs significantly slower than the rest of pydantic's validation. (Approx 75% of the time was spent in email validation.)

Removing it gives us a truer measurement on the performance of pydantic's internals.
