feat: support numbers as v9 Option values

[smhigley]

Previous Behavior

The value prop on the v9 <Option> component only accepted strings. Since this is only used for matching with selectedOptions and as data on onOptionSelect, we should be able to accept number values as well.

New Behavior

allows value to be string | number (and updates associated types & tests)
