tempDir does not allow dynamic parameter

[MartinMystikJonas]

Last version introduced check that tempDir is string here:

translation/src/DI/TranslationExtension.php

Line 74 in 5788c79

if (!is_string($tempDir)) {

In some setups we use tempDir as dynamic parameter and this ends up with:

Contributte\Translation\Exceptions\InvalidArgument: Container parameter "tempDir" must be a string.
   in src/DI/TranslationExtension.php(75)
