fix (frontend): Partially fixes lineage issues and dataset API handling

[cptran777]

This PR fixes the following issues:

• The attributes of the current dataset in the lineage relationship module are not displayed correctly #1827
• Does the frontend page no longer display the dataset description #1823

Both of which likely stem from the same root cause: that the datasets response for the open source midtier (datahub-frontend) no longer matches with how we are handling datasets in datahub-web internally. This PR doesn't create a perfect parity between the two but should bring us a little closer to how components are currently consuming dataset data.

Upon testing, it looks like the lineage issue is solved and other components are currently working fine.

Will rely on automated tests with the build for the rest.
