[Idea] Add example of custom tab content for demoproductform2 example module

[Oksydan]

The problem

It would be nice to have an example of how to add custom content to product page v2 custom tab feature. Demoproductform2 module only shows how to add MoneyType in CustomTabType. This tab is likely to be used by many developers in the near future and an example of how to add a custom template to this tab could be very useful, since it is not so obvious how to do it correctly.

The solution

Add an example of how to add custom tab content template in the demoproductform2 example module.
