Registering a new GlyGenKG (#497)

* Create documentation for GlyGen KG

Added documentation for GlyGen KG including metadata and contact information.

* Registering GlyGenKG

* Clarify description of GlyGen KG

Updated the description to clarify the inclusion of genes related to glycoproteins.

* Comment out sparql and tpf URLs

+GlyGen KG is the RDF knowledge graph built from [GlyGen](https://www.glygen.org/), a data
+integration and dissemination project for carbohydrate and glycoconjugate related data. GlyGen
+brings glycoscience data together with glycan, protein, gene, and disease data.
