in text: "bruteforce" > "brute force"

In description text we should use correct spelling which is "brute force" or "brute-force", not "bruteforce".

In other parts of the documentation, "brute force" is used: https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/bruteforce_configuration.html
