IGAPP-1050: Support versioned page slugs

[jira-to-github-migrator[bot]]

Blocked by cms, on native we need a previous_paths property, see https://chat.tuerantuer.org/digitalfabrik/pl/itp6do3zkpgrmf114hq7kiw4sa. CMS Issue: https://github.com/digitalfabrik/integreat-cms/issues/1587.

As a user I want to be redirected to the correct url instead of seeing a not found error if the url of a category changes and my old url is therefore not correct anymore.

Acceptance criteria:

• Old urls of categories are redirect to the new ones
• The share url is set to the new url

Test information:

• go to https://integreat.app/testumgebung/de/test-slug-versionierung-new (new url, works)
• go to https://integreat.app/testumgebung/de/test-slug-versionierung (old url, doesn't work)

Additional information:

• adjustments on native probably need to happen here in pushCategory to find a category not only by path but also by path in the new previous_paths property
• the path has to be changed to the new path in pushCategory as well
