Breaking: #65317 - TypoScriptParser sortList sanitizes input on numerical sort

See forge#65317

Description

When calling the := sortList() with a "numeric" modifier of the TypoScript parser with a string, the sort() method differs between PHP versions. In order to make this behavior more strict, a check is done before the elements are sorted to only have numeric values in the list, otherwise an Exception is thrown.

Impact

An exception is thrown if non-numerical values are given for a numeric sort in TypoScripts sortList.

Affected Installations

All installations using sortList numeric with non-numerical values.

Migration

Either remove the non-numerical values from the list or change the sort order to be non-numerical (ascending / descending).
