Slider Track Height CSS Variable

[DarkKooky]

When looking at the Slider CSS Variables, the --slider-track-height is said to be applied, as the name implies, to the slider track height. However, it is also used to configure the slider border-radius but isn't mentionned in the documentation.

To verify this, open Obsidian's Settings > Appearance and inspect the Font size slider to see the following styling.

The double use of the variable should be mentionned or be changes for better styling modularity.
