Allow you to attach multiple message links when submitting a request to trust and safety.

It's a bit annoying that you can only attach 1 message link when submitting a request to trust and safety, I believe it should be made that you can attach multiple message links, as well lets face it, people aren't going to say ToS violating things in a single message, most likely they are going to do it in multiple messages, and also Discord's team can't check attachments for some reason, so it would be better if we could just add multiple message links and the team at Discord can piece it all together and deal with the situation.
