[UIDS] Don't allow non-number characters in number Input

[gabescarbrough]

Description

Firefox has longstanding bug where input's with type number allow non-number characters

Since our Input is built on top of the browser input this bug is true of our inputs as well

Makes sense to fix this on our end since I don't see Mozilla fixing that bug anytime soon

User Stories

• As a user, I want number inputs to only allow numbers so that I can't enter invalid values.

Acceptance Criteria

• Can't enter non-number values into <Input type="number" />
