Pull config values into dataset overview drawer (#1814)

This PR adds multiple data to the dataset overview drawer provided by the config endpoint and formats them accordingly.  The appearance of this new data is contingent on `dataPortalProps.corpora_schema_version === "1.0.0"`

For QA launch cellxgene with a remixed dataset and click on the button in the upper left-hand corner or the updated button in the info menu.
