French L10N for the title of daily notification email is incorrect: "Modifications de Confluence dans les 24 dernières heures"

Daily email notifications localized in French have an incorrect title, showing a   HTML entity escaped:

{{

Modifications de Confluence dans les 24 dernières heures

}}

The following line in /confluence/WEB-INF/classes/com/atlassian/confluence/setup/atlassian-bundled-plugins/confluence-fr_FR-plugin-1.23.1/com/atlassian/confluence/core/ConfluenceActionSupport_fr_FR.properties (line 6815 in version 1.23.1 of the French L10N plugin):

 daily.report.title=Modifications de Confluence dans les 24 derni\u00e8res heures

needs to be changed as follows (replace the   entity by a regular space):

 daily.report.title=Modifications de Confluence dans les 24 derni\u00e8res heures
