Fix: editing responses on a survey

[Stef-Rousset]

🎩 Description

This PR updates the Gemfile.lock and package-lock.json to get the latest version of decidim that includes this backport decidim/decidim#16809 of the bug fix on editing responses for a survey.

This PR removes the override of FindAndUpdtaeDescendantsJob, because of the evolution of the code in 0.31 (notably 2 arguments instead of one in perfom method that causes error). The necessity of the override in 0.31 should be study in another card (cfhttps://github.com/orgs/OpenSourcePolitics/projects/26/views/1?pane=issue&itemId=186116483&issue=OpenSourcePolitics%7Cintern-tasks%7C443).

And eventually, it updates the proposals_index system test.

Testing

1. As an admin, create a new survey, add 2 questions. Add a display condition on the question 2 depending on question one.
2. In the settings, allow the users to modify their responses.
3. As a user, answer the survey
4. As a user, click on "Edit your responses"
5. See that you have access to the edit page (cf screenshot)
