Feature: #83912 - Specify Section in Redirect Finisher

See Issue #83912

Description

It is now possible to specify a fragment in the Redirect finisher. This allows a user to be redirected to a specific content element or relevant section after completing a form.

Impact

A section can be defined in a form definition with the fragment option. In the example below, fragment: '9' refers to the content element with uid 9. There is no need to add the # character. It is also possible to configure a custom section, e.g. fragment: 'foo'.

finishers:
  -
    options:
      pageUid: '7'
      additionalParameters: ''
      fragment: '9'
    identifier: Redirect
