Recover secrets dynamically from vaultwarden

[gmguarino]

At the moment the secrets needed for opentofu in the infrastructure directory are manually added to the .env.secrets files. We want this to be automatic.

• Log in automatically into vaultwarden (like d4g-tf)
• Create applications when deploying environment with an api key to be used by terraform
• add terraform api key to vaultwarden secret.
• recover secrets by name as secret name is the same as the directory path.
• add secrets to the correct .env.secrets file in target directory.
