QR Code payload

[peppelinux]

on the documentation, here
https://italia.github.io/eudi-wallet-it-docs/version-corrente/en/relying-party-solution.html#authorization-request-details

if you frame it with a generic lighter qrcode you see the payload in plain text, as it should be. If you frame it in the online PoC instead it appears as RAW base64.

I made some corrections to the documentation whose PR is being reviewed, I need that in the QR code we are working on the payload decoded by the lighter is clear, so that I see a result like the following

haip://authorize?client_id=https%3A%2F%2Frelying-party.example.org&request_uri=https%3A%2F%2Frelying-party.example.org%2Frequest_uri%3Fid%3Drandom-value&https%3A%2F%2Frelying-party.example.org%2Fdiscovery_uri%23that-random-fragment-we-mentioned
