examples, readme: fix typos

[ttytm]

• I would like to update the js_dom examples readme files as they contain several spelling mistakes at the moment.

  Here are the links to reduce the effort if someone wants to make a side by side comparison of the GitHub rendered documents:

• Changes I made to the main readmes editor plugins section also included spelling errors. They are corrected here as well.

This pull request improves the documentation and style of the js_dom_draw example and the main README.md file. It corrects some spelling and grammar errors, adds more details and instructions, and formats the text for better readability.

Good work.

Why is it draft? Does it need more changes?

I thought to include the updates here for examples/js_dom_cube and examples/js_dom_draw_bechmark_chart as well. I would add them when a free moment opens up later this day.
