Outdated documentation about generating examples

          > Working with ES2021 does not seem to generate that ugly JS anymore, what do you think?

That is great! Once we move on with #1340 we can also remove the workflow described here

node-wot/packages/examples/README.md

Lines 14 to 29 in 5afa858

	### Workflow
	1. Run `npm run build`
	2. Remove the following 3/4 lines in JS files of folder `dist/`
	```
	Object.defineProperty(exports, "__esModule", { value: true });
	require("wot-typescript-definitions");
	let WoT;
	let WoTHelpers;
	```
	3. Copy the according JS file(s) to
	- `<node-wot>/examples/scripts`
	- `<node-wot>/examples/testthing`
