Feel free to give me some feedback or asking for changes if required.

Thanks you =)

Description

This pull request create a new slider to better match the MaterialDesign 3 guideline. It's a small change required in one of my project and I decided to share it as I think it's usefull. The only change is the height of the active track who need to match the track height. Here's the md3 slider spec :

I follow some guideline found here and there on this repo about handeling the version 3 of material design:

• Creating a new themes for specific md3 element
• Adding to the md3 default theme
• Update the demo project

Result on the demo app :

Current master of the demo app :

Changes Made

• Create a new slider theme md3
  • Changing the height of the selected line (activeTrack) of the slider line to match the md3 guideline (So the activeTrack and the Track have the same height : 4 )
• Use this new slider them on the demo app

Additional Notes

If theses changes are validate it could be possible to do the same for the range slider (on project MaterialDesignThemes.MahApps ). But this project does not include a md3 theme so you'll have to decide if a default md3 theme file should be created or if the current RangeSlider should be updated.
