Core: Fix the nullish coalescing operator in _updateScalesRange

[50rayn]

I got this interesting warning when playing around with the project build.

src/containers/xy-container/index.ts: The "??" operator here will always return the left operand

And the compiler was right. In case config.padding.bottom will be undefined, subtraction will get NaN. The operator will be applied to the result of the subtraction but not the config.padding.bottom. So the fix was easy, just wrapping up with paratheses.

@50rayn You're right! I wonder how did we miss it. Thanks

Thanks to Vite :D .
I was trying to integrate Vite in @unovis/ts.
