Bug 24811: French SQL files "news" link fixed

This fixes a broken link in the sample news items for fr-FR and fr-CA.

Test plan:

1) Apply the patch.

2) Install the French language files - see
https://wiki.koha-community.org/wiki/Installation_of_additional_languages_for_OPAC_and_INTRANET_staff_client

3) When Koha is in French, from the home page of the staff interface go to Tools/Outils > News/Annonces, and make sure the two news items are there.
    -If not, try importing the two files into your database or reset and install Koha in French (fr-FR or fr-CA).

4) There should be a news item with the heading Et maintenant ?, click the 5th link "proposez des correctifs et des améliorations".

5) If should take you to
https://wiki.koha-community.org/wiki/Version_Control_Using_Git
and there is no 404 error, the patch has worked!
