Configure links and open them in a new tab

[coudot]

In footer we have some links:

• Plan du site
• Accessibilité
• Mentions légales

The links should be configured (with messages) and have a target _blank to be opened as new tabs/windows.

Example:

$messages['dsfr_entity_name'] = "Ministère<br>de l'agriculture<br>et de la souveraineté<br>alimentaire<br/>test";
$messages['dsfr_footer_link_1_name'] = "Accessibilité : non/partiellement/totalement conforme";
$messages['dsfr_footer_link_1_address'] ="#";
$messages['dsfr_footer_link_2_name'] = "Aide en ligne";
$messages['dsfr_footer_link_2_address'] ="#";
$messages['dsfr_footer_link_3_name'] = "Note sur les codes RH secondaires";
$messages['dsfr_footer_link_3_address'] ="#";
$messages['dsfr_footer_link_4_name'] = "Mentions légales";
$messages['dsfr_footer_link_4_address'] ="#";
$messages['dsfr_footer_link_5_name'] = "Politique des cookies";
$messages['dsfr_footer_link_5_address'] ="#";
