Support for Markdown Callouts in Exercise Description

[martin-fink]

Is your feature request related to a problem?

Sometimes, it would be helpful to give hints or tips to students, which are not easily missed. Currently, I am writing them like this:

Important: Make sure not to create bugs.

Warning: Do not use class xyz.

Describe the solution you'd like

I'd like to use callouts instead. Rendering them like e.g. Github does it would make it harder to miss important tips. Example:

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.

Describe alternatives you've considered

No response

Additional context

Currently, Artemis does not support callouts. They are rendered as normal quotes:

Great idea 👍🏻 can you check if there is a markdown plugin which can render this that is compatible with the markdown library that the Artemis client is using?

Then, it should be super easy to implement this feature

@martin-fink I've found a suitable plugin and implemented it.
@krusche can you please assign the issue to me as I cannot assign it to me myself and it seems I'm missing rights to push to the repository at the moment.
