i18n: duplicate 'translate' marking in theme-preview.html

[Akihiro Motoki]

There are duplicated and nested 'translated' mark in theme-preview.html.

               <div class="col-lg-10">
                 <div class="themable-radio">
                   <input type="radio" name="optionsThemableRadios" id="optionsRadios3" value="option1" checked="">
                   <label translate for="optionsRadios3">
                     <span>{$ 'Themable Option 1' | translate $}</span>
                   </label>
                 </div>
                 <div class="themable-radio">
                   <input type="radio" name="optionsThemableRadios" id="optionsRadios4" value="option2">
                   <label translate for="optionsRadios4">
                    <span>{$ 'Themable Option 2' | translate $}</span>
                   </label>
                 </div>

As a result, we have the following entries in PO files.

<span>{$ 'Themable Option 1' | translate $}</span>
<span>{$ 'Themable Option 2' | translate $}</span>

Themable Option 1/2 should be extracted.

The strings are in Developer Dashboard, so it can be low priority.
newton backport is optional, so I don't add newton-rc-potential tag.
