Feature Request - Support basic markdown

[jboulter11]

For example:
Title("`ClassName` is really important") would render a title where `ClassName` is highlighted like ClassName.
Text("\_This\_ is italicized") would render text where _This_ renders like This.
Words("\**What\** even is text") would render words where *What* renders like What.

I use these inline highlights a lot and I immediately was missing them when I tried using DeckUI because my title contained something I wanted to highlight.

Would this work with AttributedString?

DeckUI totally needs to have this 😊 I'll see what we can do!

Could possibly bring in https://github.com/gonzalezreal/swift-markdown-ui 🤔
