BigQuery table link doesn't fit into rest of metadata

[wlach]

I added a link to the BigQuery table view when working on the initial skeleton. With some of the recent changes, it now looks pretty out of place:

It should be an item in the table below (just after "notification email"). I would propose the following structure:

• Name: "BigQuery Table"
• Link: name of stable table name in the table view (e.g. org_mozilla_fenix.activation for fenix activation table)

You may need to update the metadata gathering step in scripts/build-glean-metadata.py to fetch the name of the stable table to put in the ping view.
