Improve Umbraco Flavored Markdown for compatibility with URL picker

[Eaglef90]

Over on the forums I asked the question of what UFM code I needed to place in a block's label to extract the "name" property of a page selected in the Muti URL Picker data type. I was then told that this is not possible to do and I would have to roll my own code causing me to have to deep dive into UFM, TypeScript, something called Lit and do a full redeploy of my site to get the code to work. This seems very convoluted and counter-productive to do just so I can get a simple built in property to display as a label. It would be nice to see the UFM expanded to be more robust and capable like the old v13 label code commands. The documentation of UFM says more functions are coming soon but it does not say what functions or target dates so I am making this official request on this for now.

For reference here is the question over on the forum and the solution given to me: https://forum.umbraco.com/t/how-to-set-a-linked-pages-name-for-block-lablel/3928
