Add inkscape-open-symbols to the Symbols gallery on the Inkscape website

[Moini]

Hi @Xaviju !

Could you please add a link to your repository at https://inkscape.org/gallery/=inkscape-symbol-set/ ? It would be great if the set could be found more easily by users.

I could do it myself, but I'd prefer if the real owner did it.

Not sure what to use for the license, though. We could add a new one, if needed.

Cannot upload just a link, it actually requires an SVG file (a symbol set). This repositiory has too many symbol sets to upload and maintain each of them. Is there an alternative to just link an external resource instead of uploading it?

What I have done for my extensions was to add a symbolic image to appear in the gallery, and to add a link in the link field of the upload form, and then to add information about how to get the actual software in the description.

There is an option to upload just a link, but I've just tested it, and it currently gives a server error... (reported here: https://gitlab.com/inkscape/inkscape-web/-/issues/526 )
