openid-client v6.x is a complete rewrite

• https://github.com/panva/openid-client/releases/tag/v6.0.0

This was released TODAY, so probably worth waiting a bit for it to bed in.

Some things to watch out for:

openid-client@6 no longer supports:

• the full cartesian matrix of response types and response modes,
• issuing encrypted assertions, decrypting assertions is limited to only a few algorithms,
• Dynamic Client Registration or Management, and
• Self-Issued OpenID Provider responses.

Also:

(Node.js) Versions 20.x and newer have all the necessary globals.
