Remove unnecessary <br/> from new.lang

You shouldn't have ```</br>```at the beginning of a sentence.

I removed it on SVN and activated the page
http://viewvc.svn.mozilla.org/vc/projects/mozilla.com/trunk/locales/he/firefox/new.lang?r1=124415&r2=124419

You can check it out at
https://www-dev.allizom.org/b/he/firefox/new/

It will require a bit more time to get to production, since it needs a pull request to get the rewrite rule in place.
Merge pull request #1 from flodolo/patch-1
