fix: #3636517 Home page not found when the default language is not English

Issue: https://www.drupal.org/i/3636517

Problem

The front page is the alias /home. The default content pins every alias to langcode: en, while core's default content importer moves each entity to the site language during a non-English install. The aliases stay English, /home does not resolve and the front page is a 404.

Proposed resolution

Remove the pinned langcode from the path items in 265 files under content/, so each alias follows its entity's language. Nothing else changes; an English install still gets English aliases.

Same fix as Horizon Aid !119 (#3629922), where a pt-pt install was tested: home 404 without the fix, 200 with it.

How to test

1. Install Drupal CMS with the The Rightup template and French as the default language.
2. Open / and the main menu links: no 404.
3. Repeat in English: unchanged.

Remaining tasks

• Test this project on a non-English install (not done yet; only Horizon Aid was tested).
