Duplicate key _sys_et_txt_body_manage_approve in Russian language file

Hi,

I've found a duplicate key in the Russian language file for email templates, in UNA version 14.0.9.

File location:

modules/russian/data/langs/system/ru.xml

Duplicate entries are found at lines: 2599 and 2645

<string name="_sys_et_txt_body_manage_approve"><![CDATA[]]></string> 
        <string name="_sys_et_txt_body_manage_approve"><![CDATA[{email_header}
<p>У команды модераторов есть к вам вопрос о '{content_title}':</p>
<p> </p>
<p>{notes}</p>
<p> </p>
{email_footer}]]></string>

This duplicate key may lead to unexpected behavior or issues when rendering emails. In the English version of this file, the key appears only once, as expected.

Please review and fix this in the official language package.

Thanks!
