SRE Telegram group images do not have challenge titles

Andrea is not able to wrap the name of the challenge on the TG images anymore.

This currently affects The ZK challenge, tokenization challenge and oracle challenge.
Personally, I don't think it matters that much because the images are barely readable but I told @rin-st I would create the issue so we can track progress if this is deemed important.
