Add Twingate as a Windows FMA (#36949)

This pull request adds support for the Twingate Windows application to
the maintained apps system. The main changes include adding metadata and
installer information for Twingate on Windows, updating the aggregated
apps list, and providing install/uninstall scripts.

**Addition of Twingate Windows app:**

* Added a new input file `winget/twingate.json` with metadata for the
Twingate Windows app, including installer details and categorization.
* Created an output file `twingate/windows.json` specifying the
available version, installer URL, SHA256 hash, upgrade code, and
PowerShell scripts for install and uninstall operations.

**Updates to app listings:**

* Updated `apps.json` to include Twingate for Windows, with platform
information and description.
