added HQ svg

[Chewbakka-Wakka]

As per #1789

With this SVG in use we can drop the package "hicolor-icon-theme" from all Linux builds (when updated) from OS requires. The SVG can be used instead of one of the various fixed png loaded files for desktop icon.

[past-due]

A couple of questions / concerns:

• This SVG file isn’t actually a vector SVG - it appears to just be an SVG container that embeds the PNG file directly. How is this superior or different from us installing the PNG?
• The only place that we reference the “hicolor-icon-theme”, that I can see, is in the Flatpak’s install location of an icon .png - and IIRC that’s recommended for Flatpaks. (The Flatpak uses the Freedesktop Runtime, and hicolor is the default fallback theme by the spec: https://askubuntu.com/a/300155)

Implementations are required to look in the "hicolor" theme if an icon was not found in the current theme.

Thanks for finding my mistake, you are correct.
I'll get this fixed to be a vector SVG.
