TYPO3 Core

Since pages_languages_overlay is migrated to pages the alias value changes when adding a translation.
The alias field is used for links and can replace the page id, when the alias changes for translated pages,
links cannot be resolved anymore correctly. The alias field is also not editable for a translated page.

Steps to Reproduce:

- Create a Page
- Insert alias like `home`
- Translate page to a different language

Actual behavioir:

- Default page alias => `home`
- Translated page alias => `home0`

Expected behavioir:

- Default page alias => `home`
- Translated page alias => `home`
