Remove "Full Name" option from Concordia bot

[erasmus]

Description Public reveal of full name seems excessive. Remove until clear benefit is established.

Change request:

1. Change the option on the UI to "Successful ID verification (without revealing name) - Requires Concordium testnet identity and account"
2. Change format!("\n- Real name: {full_name}")); to format!("\n- User has been verified with ConcordiumID")); https://github.com/Concordium/concordium-web3id/blob/main/examples/bots/discord-bot/src/main.rs#L106C41-L106C48
3. Check other places that may require change

The Concordia bot showcases the web3ID capabilities as a demo application. It can be used to create social reputation by linking a social media account e.g "max_1234" with a real-world identity e.g. "Max Mustermann". This verification is done voluntarily by users.

The consequences of removing the real-world identity (full-name) verification are:

• Leaves Concordia demo to only be able to showcase how two social media accounts (discord and telegram) can be linked, but no reputation from a real-world identity can be gathered.
• The demo does not show the ZK proof generation/verification anymore.
• The demo does not show anymore how web3ID credentials and identities in Concordium wallets can work together/interact.

We should consider these consequences and have an alternative demo to showcase these capabilities before changing the demo.

The example case still works as its confirming the user on Telegram and Discord is the same user.

There is no need to disclose the full name in public, no one is using their full name on telegram or discord.

The use case was to show that you can prove that a person on Discord and Telegram is the same person and that proof is still valid even if you do not disclose the full name, you can still confirm that you have verified it in the proof without disclosing the information.

Indirect proofs utilizes the power of zero knowledge proofs and demonstrates them far stronger than an example of disclosing or revealing the persons full name, because then you are giving away knowledge in the proof instead of utilizing the zero knowledge proof.
