fix: Update a translation key to match correct string

[mister-ben]

Description

The lang files were translating "all settings to the default values" instead of "restore all settings to the default values".

Specific Changes proposed

• Updated the key in all lang files already using it
• Updated the French translation and added some further missing German translations

@h0lysl4y3r the Slovakian translation probably needs an update now.

Requirements Checklist

• Feature implemented / Bug fixed
• Change has been verified in an actual browser (Chome, Firefox, IE)
• Reviewed by Two Core Contributors

I wonder if the string should just be all settings to the default values. I think it was supposed to be so that the screen reader would read: Reset all settings to the default values but if we add restore into the translations, it'll be doubled up and it'll read Reset restore all settings to the default values.

Ah, but that wouldn't work for some languages because of the word order.
