Add changelog section

Is your feature request related to a problem? Please describe. It is useful to include a changelog in projects (see Keep a Changelog). Maybe this could be encouraged by including it in the generator?

Describe the solution you'd like Add a question that asks for changelog URL, and add a changelog section to the README if the URL was provided. The changelog section would be short and just point to the URL provided, similarly as done in Contributing section.

Describe alternatives you've considered User can either decide not to include it, but that's not very community-friendly. Or user can add the changelog section manually. However, changelog is applicable to likely the large majority of projects that use this generator, so it could be meaningful enough to provide it out of the box.
