Feature: #92337 - Allow translatable labels for bookmark groups

See Issue #92337

Description

The user TSconfig options.bookmarkGroups option allows to configure the bookmark groups that can be accessed by the user. In addition to that, it’s also possible to define custom labels for each group as simple string. Extended TSconfig syntax now allows the LLL prefix for the use of language labels.

Example

options.bookmarkGroups.2 = LLL:EXT:sitepackage/Resources/Private/Language/locallang_be.xlf:bookmarkGroups.2

Impact

It is now possible to use custom language labels for bookmark groups.
