align german loginWithLabel translation with Apple Guidelines

[Steffen911]

Changes

Update Germany translation for loginWithLabel to comply with Apple's Design Guidelines. The standard translation got rejected in the Appstore Review:

Your app offers Sign in with Apple as a login option but does not use the appropriate Sign in with Apple button design, placement, and/or user interface elements. Specifically:

• The  Sign in with Apple says “ANMELDEN MIT APPLE” but should use the following localized version: “Mit Apple anmelden”.

Next Steps

Please revise the Sign in with Apple buttons in your app so that they are compliant with the App Store Review Guidelines and the Sign in With Apple Human Interface Guidelines.
