link to licence in ontology information is incorrect

[rombaum]

I spotted that the link to a licence information, which is located in this case in github, is not resolved correctly in the ontology information. The linked text also looks strange.

In OLS3 this issue didn't appear since there was only the url presented.

The url for the licence provided by the ontology is the following:

https://github.com/maelstrom-research/maelstrom-taxonomies/blob/master/LICENSE.md
