Unify writing of the passbolt name in the German localization

[stromhalm]

Hey there,

this change fixes an issue with the German localization. In the email subject, the service is called Passwort instead of passbolt. Additionally, I noticed that the passbolt name was inconsistently written as either passbolt or Passbolt throughout the repository. This unifies the writing as passbolt in the de_DE locale, consistent with the English naming.

Fix to de_DE locale
