Add german translation for "Restore Wallet..." #26187

<!-- Describe the issue -->

Using the german locale, the file menu item "Restore Wallet..." is missing a translation.

<!--- What behavior did you expect? -->

Instead of "Restore Wallet..." I would expect the german translation "Wallet wiederherstellen..."

<!--- How reliably can you reproduce the issue, what are the steps to do so? -->

Windows 7, 64-bit, German

<!-- What version of Bitcoin Core are you using, where did you get it (website, self-compiled, etc)? -->

bitcoin-24.0rc1-win64-setup.exe binary from bitcoincore.org/bin

24.0rc1 misses the recent translations. They will be pulled into 24.0rc2 in #26141.
