Per {T328060}, capture:
> * Everything the [[https://gerrit.wikimedia.org/r/plugins/gitiles/schemas/event/secondary/+/9294d47418317c663b29112fded2a6a06dc2142a/jsonschema/analytics/legacy/helppanel/current.yaml|HelpPanel schema]] currently captures about that event (e.g. time, platform, wiki, user ID, edit count, etc)
> * That the user is seeing this “try a Suggested edit” dialogue. This should be reflected in the `type` value in the `action_data` field (because the `context` and `action` fields already reflect that it's an impression of the post-edit dialogue).
> * The action the user took, whether it was “try suggested edits” or “no thanks”.
That is:
* Log the following values:
** on impression: `context=postedit-nonsuggested,action=postedit-impression`
** on closing (this can happen via the "No thanks" button, the X icon, the Esc key, clicking outside - I assume it's OK not to differentiate since we don't do that elsewhere either) `context=postedit-nonsuggested,action=postedit-close`
** on clicking the "Try suggested edits" button: `context=postedit-nonsuggested,action=postedit-link-click,action_data=suggested-edits`
(and `savedTaskType` in `action_data` will become optional since we don't have it)
* on collapsing/expanding the postedit dialog: `context=postedit-nonsuggested,action=postedit-collapse` / `context=postedit-nonsuggested,action=postedit-expand`
* `help_panel_session_id` takes the same value as `session_token`
* `editor_interface` will take the value `not-known` (it can probably be recovered during analysis by checking the change tags on the user's last edit)
* update schema docs for `savedTaskType`
