Description

Long error messages can be tricky and hard to understand at first glance

For example

the trait bound `poise::serenity_prelude::Timestamp: From<Result<poise::serenity_prelude::Timestamp, InvalidTimestamp>>` is not satisfied
the following other types implement trait `From<T>`:
  `poise::serenity_prelude::Timestamp` implements `From<&poise::serenity_prelude::Timestamp>`
  `poise::serenity_prelude::Timestamp` implements `From<DateTime<Tz>>`
required for `Result<poise::serenity_prelude::Timestamp, InvalidTimestamp>` to implement `Into<poise::serenity_prelude::Timestamp>`

I think it'd be better if we could display this error in a prettier format like in the vscode extension
https://marketplace.visualstudio.com/items?itemName=yoavbls.pretty-ts-errors

So instead we could have something like the full compiler diagnostics referenced inline, or something like
