Re-Run the outbound links analytics script

[NoopDog]

Now that we have had the outbound links collecting for a while. Run the report for the last 30 days and lets review the spreadsheet together.

Track both external and internal links, and add a column to the report that marks whether a link is internal or external. Need:

• Internal / External
• Current Page
• Clicked Page
• # Total clicks
• # Unique users clicking the link

@NoopDog I've pushed the changes to the script to generate the sheet you specified to the old #3202 branch, the PR is here. It will need to be changed after DataBiosphere/data-browser#4272 is merged, since it renames the outbound_link_click event, so it could be good to wait on that before merging this!
