[@mantine/core] NumberInput: Allows the "-" symbol in an empty NumberInput

[BWsix]

Fixes the bug in NumberInput raised in the discord bugs channel

Is NumberInput not allowing the "-" symbol in an empty NumberInput expected behavior? Currently, you are unable to type "-" in an empty NumberInput unless you first put a number then go back and place the "-" before it

Changes:

• You can now type - in an empty NumberInput.
• If - is the only thing in a NumberInput, the value will remain undefined, and the NumberInput will be cleared when the onBlur event fires.
