Jsdom does not support TextEncoder and TextDecoder

[Max Chopart]

After bumping jsonld, 6896af0, Jsdom also had to be bumped, because it did not support the newer version of jsonld.

Jsonld needs Textdecoder, but is not supported by the bumped jsdom (see jsdom/jsdom#2524). Workaround was found here: jsdom/jsdom#2524 (comment), but the issue in jsdom/jsdom#2524 is still open, so possibly there will be support added soon

[Miroslav Blaško]

Although the issue is closed, it is a workaround that should be removed later when Jsdom supports TextEncoder/TextDecoder.
