Add a nice UI for the dummy Relying Party

[lmuntaner]

Motivation

Main motivation is to deploy the dummy relying party to mainnet so that developers can get a grasp of the feature fast.

The idea is to link the RP in the dev docs for discoverability.

Changes

• Add mainnet network to dfx.json.
• Bumped the II version used.
• Install tailwind to dummy-relying-party and use it in index.html to build a nice UI.
• Change the dom manipulation of the JS file to be adapted to the new UI and offer a nice UX.

Tests

Relying party can be test here: https://l7rua-raaaa-aaaap-ahh6a-cai.icp0.io/

Todos

• Add entry to changelog (if necessary). Not necessary. No new functionality is added to the SDK.
