Alternative downloads section is confusing

[gmethvin]

All the newer play versions point to activator on the download page. I don't think that makes sense, as the links don't correspond to the Play versions at all, and it's really unclear how you would use activator to create a project with that specific play version.

We can add a link called 'instructions' with each of the version heading (eg. 2.6 [link]instructions ) so that we can point the user to the installation instructions for each minor version, in this case https://www.playframework.com/documentation/2.6.x/Installing

Approach simiar to this
