3 mistakes in french translation

[charleswroy]

Good afternoon @noam148,

There are 3 misakes in the french translations:

'Are you sure you want to delete this image?' => 'Voulez-vous vraiment effacer cet\'image?',
'Are you sure you want to detach the image?' => 'Voules-vous détacher cet\'image?',
'Upload' => 'Upload'

Should be:

'Are you sure you want to delete this image?' => 'Voulez-vous vraiment effacer cette image?',
'Are you sure you want to detach the image?' => 'Voules-vous détacher cette image?',
'Upload' => 'Télécharger'

Thank you so much for the extension!
