Enhance Documentation for Registering Plugins on the Mattermost Webapp Sidebar

[azigler]

Description

We've identified a need to refresh and enrich our documentation, specifically around the development process of registering a plugin on the Mattermost webapp sidebar. Currently, developers seek clearer, more direct guidance on integrating their plugins into the Mattermost UI, with explicit examples and reference links. This documentation update will aim to fill this gap by providing comprehensive, step-by-step instructions and examples to enhance the developer experience. This issue arises from a real-world example where we assisted the CEO of Parabol in turning their integration into a plugin, demonstrating the practical necessity of this documentation.

Enhancing this section of the documentation will not only facilitate a smoother development experience for our integration partners but also encourage more robust and seamless integrations within the Mattermost ecosystem.
