Add Inkscape as a Windows FMA (#37386)

This pull request adds support for managing the Inkscape application on
Windows. It introduces new configuration files and updates existing
outputs to include Inkscape as a managed app, complete with installation
and uninstallation scripts.

**Addition of Inkscape for Windows:**

* Added a new input configuration for Inkscape in `winget`, specifying
installer details and default categories in `inkscape.json`.
* Created a new output file `inkscape/windows.json` with version
information, download URL, SHA256 hash, install/uninstall scripts, and
upgrade code for Inkscape 1.4.2.

**Updates to application listings:**

* Updated `apps.json` to include Inkscape for Windows as a managed app,
with its platform, slug, unique identifier, and description.
