Add release that inclues all 1.1 builds

[daz96050]

I recently went back to 1.1 so that I can play space exploration, but it looks like the releases page is just full of random releases.
And the linked Factorio Prints page from the documentation below doesn't display old releases.

Could you create a release that contains all of the blueprint books from 1.1 together, instead of peacemeal books or something I have to build?

You can search for "1.x" in the releases list to find the BT books. The SBF release seems to be missing, however.
