Reword link to current .json & versions for easier maintenance

[janbrasna]

Change the order in paragraphs linking to the currentmost symlink, and if needed showing how to link to an exact version — changing the wording "as an example", without the need to bump the version every single time the specs update.

Future possible improvement is a link to every single version .json from the version history (or linking to github release page with a link there possibly…)
