Background
For the work done on Editors view T408635: Develop Editors view of Contributions tab, we updated the tables in the Contributions tab to be 'Edits' (the current table we have that shows contributions) and 'Editors' (data on impact per editor). We need to consolidate language on other parts of the tab for consistency.
Specifically changing from 'Participants' to 'Editors' on the summary, and from 'Contributions made during this event' to 'Edits' on the Edits table.
Acceptance criteria
- Given that someone is viewing the aggregated summary of the Contributions tab,
- Then, for the first data point, they should see 'Editors' instead of 'Participants'
- Given that someone is viewing the 'Edits' table/view on the Contributions tab,
- Then, the header for that table should be 'Edits' instead of 'Contributions made during this event'.
