Breaking: #93081 - Removed fetching translation file mirror from typo3.org

See Issue #93081

Description

The process of downloading translation of XLF files has been simplified. The URL https://localize.typo3.org/xliff/ is always used instead of download a static XML file from typo3.org and persisting the URL in the registry.

Impact

The URL https://localize.typo3.org/xliff/ is always used and typo3.org is not contacted anymore.

If any extension has overridden the information in the registry, this path won’t be taken into account anymore.

Affected Installations

Any TYPO3 installation which uses a different URL to fetch translations of TYPO3 core or any extension.

Migration

Use the existing event ModifyLanguagePackRemoteBaseUrlEvent to change the URL used to fetch translations.
