Fix regression in jwt url parameter by awaiting async getAdditionalAuthHeader

[cwperks]

Description

A regression was introduced into JWT auth in the 2.4.0 release that prevented authentication with the JWT backend via the url param due to a signature change in the getAdditionalAuthHeader function. See this comment for details: #872 (comment)

This PR introduces a file called after_env.js which is needed to get beyond an issue ReferenceError: TextEncoder is not defined when trying to import SignJWT from jose.

The solution was suggested here: inrupt/solid-client-authn-js#1676 (comment)

I'm not sure if this is the best way to get beyond the problem and open to anyone's suggestions.
