Fastlane i18n

Please add the Fastlane app metadata as component on Weblate to make it translatable here https://hosted.weblate.org/projects/simplex-chat/
You may check how this made in Conversations app.
The F-Droid doesn't make an auto-translation of descriptions so usrs there may not understand what the app is doing and what is it's advantages.

Meanwhile here I added one translation but also tried to simplify the description itself to make it shorter and easier to read and trannslate.:

• removed link to "Security assessment was done by Trail of Bits in November 2022" because it's not that important to have it in a description on app store.
• Removed many repeated "End-to-end". The e2e may sound short in English but may be very long in other languages.
• Removed repeated "SimpleX" e.g. the SimpleX Chat features: become just Features:
