[Schedule] Timeline view

[laugri]

Hello !

We have started using the Schedule component in our product and it's great.
We'll need to use a timeline view at some point and I think it would make a great addition to Mantine.

Some examples to illustrate what I mean :

• https://planby.app/#examples-navigation
• https://www.npmjs.com/package/react-calendar-timeline
• https://demo.mobiscroll.com/react/timeline/calendar-timeline

It will be added in 9.4 release at the end of June

Let's go ! 🚀🚀
