### Summary
This PR creates a pluralized activity log in the case where a user
deletes multiple saved queries.
I had considered updating the default template to better support
pluralization, but when reviewing the various activity log types, I
think queries are the only type that would benefit from this. So I chose
the easier option here which felt less risky.

### Test Plan
I added a unit test for this.
Additionally, I deleted multiple saved queries in my local installation.
Here's the resulting log, showing the proper pluralization:
