Should the Extension store be changed to Apps or App Store or

The Jami App Store, inspiration from Flathub which says The Linux App Store

Thank you

@xjouslindenoray cf. comment at https://review.jami.net/c/jami-client-qt/+/25501

1. Should Last update have a trailing d to become Last Updated?
2. Is there a date associated with this string? If so, should the string include the date as a variable, i.e. Last updated: %1

• en (source): Last updated: %1
• fr: Dernière mise à jour : %1

Inspiration from https://addons.thunderbird.net/thunderbird/addon/cardbook/
