[BUG] Correct way to set up the system date

[eshcheglov]

In the installation documentation (docs-fidoiot/docs/installation.md), it suggests setting the system time by making a web request and parsing the response. Honestly, it's the craziest and most absurd way of setting the system time I have ever seen. This command can even make things worse if the system already has the correct time set up using NTP

I suggest doing it properly by providing a direct link to the Ubuntu documentation

Another way is to run timedatectl set-ntp true command, but it also has some drawbacks (e.g user may have another NTP client installed different from timedatectl one)
