Use a dist README fixture kept in the jQuery repository instead of modifying
an existing one. This makes the jQuery repository the single source of truth
when it comes to jQuery releases and it makes it easier to make changes to
README without worrying how it will affect older jQuery lines.
The commit also ES6ifies build/release.js & build/release/dist.js

(cherry picked from commit 358b769a00)
So far, only browser-based JS files were required to be in strict mode (in the
function form). This commit adds such a requirement to Node.js scripts where
the global form is preferred. All Node.js scripts in sloppy mode were
converted to strict mode.

Without this change passing `--dry-run` to jquery-release still pushes to the
jquery-dist repository which is dangerous as one can assume `--dry-run` to be
safe from external side effects.
