Fix: DO-3869 input component bug

[patricia-causalens]

Motivation and Context

User found that if they type 10. and then tried to backspace, then it didn't go to 10

Implementation Description

The issue was found that when we updated the input to 10., we keep the value at 10, so when the backspace is pressed the value does go to 10, but since the value hadn't changed then the useEffect was not triggered and so the input was not updated.

Any new dependencies Introduced

None

How Has This Been Tested?

Locally on storybook and by adding a test
