Describe the bug

On a Slider with marks, the mark position and value don't correspond with the thumb position. This can be easily seen on one of the Slider examples on the Mantine website: https://mantine.dev/core/slider/#styles-api

If you try to position the center of the thumb on (or as closely as possible) the 20% mark, the value is 19%. If you try to position it on the 80% mark, the value is 79%.

It seems the mark is not aligned to the center of the thumb, but slightly to the left. This may be confusing to users who try to position the thumb on a mark.

If possible, include a link to a codesandbox with a minimal reproduction

fix is to remove the transform (line 181) in mantine/packages/@mantine/core/src/components/Slider/Slider.module.css https://github.com/mantinedev/mantine/blob/b0902662c103732e3861694f98d3024b3bb1988c/packages/%40mantine/core/src/components/Slider/Slider.module.css#L181
