Similar to how we have an edit tag for Newcomer Tasks, we want an edit tag specifically for the add link subtype.
- The user-facing text for the tag should be: "Suggested: add links"
- The edit should //not// also get the "Newcomer task" tag.
- The edit tag should apply even if the user makes other changes in the editor outside of the link targets, though this is not going to be possible in the first version of the feature. Users will have to either publish or discard their link additions before using the visual editor on the article.
- The edit tag should only apply to edits made through our "add links" interface, not other edits made by the user to the selected article. In the future, we may allow users to access this suggested edit task type through routes apart from the feed on the newcomer homepage. The tag should apply in those situations, too.
