Must run AppHostBuilderExtensions.ConfigureMauiPane()

[dhq-boiler]

Hi.

Thank you for your great work. I tried to use DockLayout but something was wrong. so, I Collated your git repository(this repository) and I found it.

We have to run AppHostBuilderExtensions.ConfigureMauiPane().

I recommend putting this note in the README.md.

Thank you.
