Breaking: #84877 - Localization of page on column basis removed 

See forge#84877

Description 

The "Translate" buttons located in each column (colPos) in the page module have been replaced by one global action button per language.

Impact 

The possibility to translate each column of a page from a different source language has been removed. Instead, the whole page gets translated with the locale action.

Affected Installations 

Every installation relying on having different sources per localization is affected.

Migration 

Manually migrate any content element by changing its parent by editing the element, in case mixed sources are used.
