Add Fastlane app description metadata to Weblate

[yurtpage]

The Fastlane app metadata description also needs to be translated, especially for F-Droid because it doesn't offer an auto-translation.

So please go to the https://hosted.weblate.org/projects/dicio-android/ On left click on plus "Add new translation" component.

• Name: metadata
• Version control system: "Git" or "GitHub pull request"
• Source code repository: use weblate://dicio-android/strings
• Optional Key filter: ^(?!changelogs/.*$).+$ to exclude changelog from translation
• Press Continue

Once created go to the component's Settings / Version Control and change "Merge style" to "Merge"
