ui_input: Adjust step values for Font Weight stepper (#40408)

# Why

While playing with new Settings UI I have spotted that changing font
weight requires a lot of clicks. This is also a bit more annoying due to
lack of ability to enter the desired value by hand.

# How

Adjust step values for Font Weight stepper, the default increment has
been changed from 10 to 50, to cover (defined in spec `950` weight)
which some fonts might use, small step has been changed from 5 to 10,
and large step from 50 to 100.

Release Notes:

- Adjusted default step values for number input UI element used for
changing Font Weight in Settings UI.
