Set row aria-label for search results

[mikejritter]

What does this do?

• Sets the row label using the data from the highest order column

Why are we doing this? (with JIRA link)
Jira:

• https://collectionspace.atlassian.net/browse/DRYD-1308
• https://collectionspace.atlassian.net/browse/DRYD-1310

The labels were previously only 'row' which is not descriptive of the row itself. This adds a label based on the example DRYD-1308 to each row in the SearchResultTables.

How should this be tested? Do these changes have associated tests?

• Run npm run lint and npm run test as a sanity check
• Run npm run devserver --back-end=https://core.dev.collectionspace.org
• Run a search and look at the resulting table
  • For each row, an aria-label should exist that reads something like {primary-column-data} selected row {index} of {total}
  • The aria-label is attached to the <a> of the row as it has role=row

Dependencies for merging? Releasing to production?
This adds intl as a prop to SearchResultTable, which should be fine as it is already handled as part of the SearchResultTableContainer.

Has the application documentation been updated for these changes?
No

Did someone actually run this code to verify it works?
@mikejritter tested w/ core.dev as a backend
