Design patterns in Vim9script

[Yegappan Lakshmanan]

Hi all,

I have created a repository (https://github.com/yegappan/design-patterns)
containing implementations of various design patterns using the latest
features in Vim9script (e.g., classes, interfaces, enums, type aliases, etc.).

I used GitHub Copilot to help generate these example scripts.

The goal of this effort is to showcase the modern capabilities of Vim9script
and provide a reference for the community.

Regards,
Yegappan
