Add Ontologies Indexing Result at the end of pipeline

[haideriqbal]

At the moment, the only way to know if the ontology has been indexed is to review the logs of our data processing pipelines and see if it was processed without errors.

Its a time-consuming process and not at a glance shows which ontologies are not there in OLS.

We can implement a mechanism where, at the end of the RDFtoJSON step in our pipeline, we see the result, which may be in a tabular format showing which ontologies were indexed and which failed to index.
