Class ons-grid__col--sticky needs documentation

[adi-unni]

There is a class ons-grid__col--sticky in the design system grid which allows a column of a grid to be sticky whilst the page is scrolled. There is no documentation around this in the grid section of the service manual and a mention is there in the table of contents page. There is a new VR example that can be used example-page-table-of-contents-stick-full-page for creating this documentation.

@OscarJackson Can we take you through this change so you understand more about this and then implement the relevant documentation?

@alessioventuriniAND Yh sure, shall we stick a meeting in for this and the prototype kit this week/next week?
