Add $NEXT_{PATCH,MINOR,MAJOR}_VERSION_{PATCH,MINOR,MAJOR} variables

[mkurz]

In our use case just having the full version string available in the template isn't enough.
E.g. $NEXT_MINOR_VERSION will render the full e.g. 2.8.0, but want to render headings that just contain "2.8" (Like "What's new in Play 2.8?", but more importantly we have links to our docs that look like

• https://www.playframework.com/documentation/2.8.x/Home
• https://www.playframework.com/documentation/2.8.x/Migration28

So we need to be able to render versions like "2.8.x" or just "28".
With this PR we can do this via: "$NEXT_MINOR_VERSION_MAJOR.$NEXT_MINOR_VERSION_MINOR.x" and "$NEXT_MINOR_VERSION_MAJOR$NEXT_MINOR_VERSION_MINOR"

However, formatting fails, can someone please run yarn prettier && yarn lint --fix && yarn build for me on this pull request? I don't use this tools and want to avoid to download and install it just for this PR (I never develop js/node.js)

From the tests, I cannot see that this has added the desired variables 🤔 and how you want to use it.

Use docker with a node js container with an interactive shell

docker run -it --rm -v ${PWD}:/src -w /src node /bin/bash
yarn
yarn prettier && yarn lint --fix && yarn build
