Translation issue in notice

[AdamSGit]

I set up TGM in my theme, and added translations directly from the provided languages dir in TGM. Translations I use are french.

As you can see in the capture above, there are two translation issues :

• The notice text isn't translated (This theme require...)
• On the link, both singular and plural string are concatened together

Here is my sample code (took the default)

$plugins = [

    // This is an example of how to include a plugin bundled with a theme.
    [
        'name'               => 'WooCommerce',
        'slug'               => 'woocommerce',
        'source'             => get_template_directory() . '/lib/plugins/woocommerce.3.6.5.zip',
        'required'           => true,
        'version'            => '',
        'force_activation'   => false,
        'force_deactivation' => false,
        'external_url'       => '',
        'is_callable'        => '',
    ],
];

$config = [
    'id'           => 'mytheme',
    'default_path' => '',
    'menu'         => 'tgmpa-install-plugins',
    'has_notices'  => true,
    'dismissable'  => false,
    'dismiss_msg'  => '',
    'is_automatic' => false,
    'message'      => '',
];

Let me know I you need further informations.
