Add Form Name component to Umbraco Flavored Markdown

[BatJan]

Updated the UFM docs with the Form Name Component and added a table showing the names and their syntax to make it quicker to skim and figure out how to use if one has read the docs before but just can't remember the template syntax.

📋 Description

Added information about the Form Name UFM component - Also added a table of available/built-in components to quicker get an overview. Perhaps the form description needs to mention that it of course only applies if forms is installed. But I feel like this option belongs in this part of the documentation too. I was personally about to roll my own custom version until a fellow Umbracian pointed me towards the Umbraco Forms docs for this :)

Thanks @BatJan ! 🙏

I added a single suggestion.
Would you mind applying the changes to the article under version 18 as well?

[BatJan]

@sofietoft I made the suggested change and I've done a PR for v18 here #8048 😇
