Error message during XML import if format version is wrong is not shown

[noeol]

l10nmgr Version: 11.2.0
TYPO3: 11.5.34
PHP Version: 7.4

Error: If the format version of the XML import file does not correspond to the required version, no error message is shown. The user can therefore not recognize what the problem is when trying to import an old XML format version (e.g. 1.2 from l10nmgr v9.2 created under TYPO3 v9.5) .

How to reproduce: Simply change the version from 2.0 to 1.2 in the XML file (see <t3_formatVersion>) and try to import it.

Current state	How it should be
