Provide unaryMinus operator for CSSSizeValue

[LouisCAD]

Hello!
I think it'd be great to be able to negate any CSSSizeValue.

Example use case where I try to negate the margin of the :before pseudo element to have a special border effect (using gradients on background):

val borderSize = 2.px
"$self:before" {
    margin(-borderSize)
    // other code
}

Hey @LouisCAD! It looks like this was shipped with https://github.com/JetBrains/compose-jb/releases/v0.5.0-build270 (check out this issue - #921)

True, thank you!
I updated and removed my extension.
