Create purls for a new ontology project

[Hannah-Doerpholz]

In our project, NFDI4Plants, we created an ontology that we are using in our tools. We auto-create purls based on the obolibrary purl pattern and would like to make the links direct our users to a specific lookup service. I tried to add the correct configuration for the custom term browser in the obo.yml file already, but please have another look to make sure nothing is affecting other projects. This issue is linked to the pull request #985

Your PR is technically correct, but before projects are added to this OBO PURL system they must first be submitted to OBO and complete the review process. Please see the documentation here: https://obofoundry.org/faq/how-do-i-register-my-ontology.html.
