Refactored 'Updating' Documentation

We’ve completely overhauled the “Updating” section of the documentation to make it clearer, more concise, and easier to follow.

Task-Oriented Guides: The old, monolithic guides have been broken down into focused, step-by-step instructions for specific tasks (e.g., updating standard desktops, small devices, Chromebooks).
Clearer Navigation: The main “Updating” page now serves as a simple portal to guide you to the exact procedure you need.
Consolidated Install Steps: The process for installing component updates and desktop patches (from LAN) has been merged into a single, logical guide.

We believe these changes will make the update process much less confusing. As always, we welcome your feedback!
