An option to highlight a "Note" and "Warning" using blockquote
Problem
Github has recently announced that they are supporting highlight feature on their markdown.
I thought it would be nice if mdbook can support that out of the box. https://github.com/orgs/community/discussions/16925
Proposed Solution
e.g.
> [!NOTE]
> Highlights information that users should take into account, even when skimming.
> [!TIP]
> Optional information to help a user be more successful.
> [!IMPORTANT]
> Crucial information necessary for users to succeed.
> [!WARNING]
> Critical content demanding immediate user attention due to potential risks.
> [!CAUTION]
> Negative potential consequences of an action.

Note that mdBook already has class="warning": https://rust-lang.github.io/mdBook/format/mdbook.html#classwarning
