Add a note of URL Constructor in old Edge

[aleen42]

Summary

Add a note of URL Constructor in old Edge to specify a special behaviour.

Test results and supporting details

// Chrome, Firefox, Node, New Edge
new URL('', 'http://www.test.com?sid=1').searchParams.get('sid'); // => "1"
// Old Edge
new URL('', 'http://www.test.com?sid=1').searchParams.get('sid'); // => null

Polyfill

A possible workaround: https://github.com/aleen42/core-web/blob/main/lib/stable/URL/index.js

Thanks for your PR! I can confirm this behavior in Edge 15 and 18 through BrowserStack. I've made some suggestions to the note to include a specific version number (rather than using "old" and "new") as well as some other wording changes.

Thanks, looks good to me!
