* chore(tests): Compatibility updates to validate-renamings.js

A minimal set of updates to validate-renamings.js to make it
compatible with @hyperjump/json-schema v1.5.  The main difference
is that that package now ships ESM rather than CJS modules,
forcing the script to use import rather than require, with
various knock-on effects (no __dirname variable, must be named
*.mjs, etc.)

* chore(tests) Remove unneeded IIFE

* chore(tests): Additional tidy-up of ESM version

Now that validate-renamings is an ES module, we can do some other
cleanup to it.
