MessageList to support Markdown syntax

[guygoldwasser]

Describe your motivation

B"H
https://vaadin.com/docs/latest/components/message-list
this component use strings only.
in case of using that e.g. with AI api, would like to have the ability to get the html parsing of the markdown syntax.

e.g. ** some text ** will be replaced to some text etc.
I am aware that there is no ISO standard for that, but maybe at least easy client side integration to do the trick with e.g. https://www.npmjs.com/package/showdown

do it on server side and set html is probably discourage as it opens other security problems.

Describe the solution you'd like

E.g. some flag on MessageListItem to use some js converters into HTML

Describe alternatives you've considered

to create my own list

We are looking into this one by either enhancing the current component or introducing a new one.
