Update custom extension conditions

[benstigsen]

Description

After having tried to create a custom condition for my extension, I ran into several issues following the documentation.

There were minor errors such as true being written as strue. But there were also some major issues, like things being imported which weren't used, extending the wrong classes and in general unclear ways to do stuff.

I ran into an issue requiring many hours of debugging, reading documentation and trial-and-error, where the custom condition was extending the wrong class, leading to something like args.host being undefined, resulting in the entire extension never being permitted, never reaching the timeout.

It also wasn't being shown how to make use of match, even though a condition config type was created to allow for this.

Hi @benstigsen !

Apologies for the wait on this one.
I've run it through our developers, and everything seems to be checking out 💪

I see though, that there are some merge conflicts - most likely related to us restructuring the backoffice articles a couple of weeks back 😅
The article has been moved to here: https://github.com/umbraco/UmbracoDocs/blob/main/14/umbraco-cms/customizing/extending-overview/extension-types/condition.md

Are you up for making a new PR with the same changes? 🙈
I fully understand if you're not - just let me know, and I'll add the changes directly!
