Materialdesign: semantic-web

[ecow]

I have:

• [x] [Searched all issues](https://github.com/Templarian/MaterialDesign/issues) to make sure there isn't a request for this icon.
• [x] [Searched the current library](https://materialdesignicons.com/) to make sure the icon doesn't exist.
• [X] Only requested a single icon (or a few near-identical ones) in this issue.

Usage

To denote a Semantic web resource (RDF/linkeddata/solid)

Examples

An example from rdf wikimedia common resource

A simpler example:

The RDF logo above is deprecated, so it will not be added. We can add the Semantic Web icon, though, on that same page, so I'm adjusting this issue to add that icon instead.
