Custom title for alert

[SelfRef]

• Extension Name: marked-alert
• Extension Version: 2.1.2

Use case

Would be nice to have control of alert's title name, like in Obsidian.

Proposal

Obsidian supports Alerts just like GFM does, but extends them further to support custom titles like this:

> [!NOTE] Example
> Description=Remaps some keycodes to other keys

It also allows for one-line alerts:

> [!INFO] Docstring can be read using property `fun.__doc__`

The same syntax is already considered for GFM alerts.

This also works that way on hackmd, would be nice to have it
