Fix bug: Replace * with *? in QuantifierToken regex pattern

[christopher-hampson]

Greedy matching for the QuantifierToken appears to cause issues for patterns with more than one quantifier.

@christopher-hampson thank you for your contribution! Do you happen to have any examples where the old code had issues fixed by the new code? It would be nice to have a test case for the behavior this change is specifically addressing.

@christopher-hampson Yes, I would agree with @eliotwrobson that an additional test case to verify these changes would be preferable, if you could please provide one. This would demonstrate, in a TDD fashion, that the hypothetical omission of these lexer changes would break this new test.

Thanks @eliotwrobson @caleb531, I've added a couple additional tests to test_quantifier which seemed the most appropriate place for this but apologies if not.

@christopher-hampson it looks like the tests are failing
