If we are really going to use this for documenting our templates, the table created by the extension must contain the description/label/... in the user language.

How to reproduce:
Switch you user language to German. Visit [[:commons:Special:Permalink/102040858]]

The following is included in the sandbox.
<templatedata>
{

"description": "English template description only.",
"params": {
    "1": {
        "description": {
            "de": "Deutscher Text.",
            "en": "English text."
        },
        "type": "string/wiki-page-name"
    }
},
"sets": []

}
</templatedata>
"English text." is shown as description of parameter 1.

Expected result:
"Deutscher Text."
