Add user-agent (curl)

[nikolaev-rd]

While trying to create a simple clock kiosk using this site: https://time.is/clock/Moscow found, that in case curl requests are forbidden:

curl -sL -b cookiefile -w "%{http_code}\\n"  https://time.is/clock/Moscow -o /dev/null
403

Details:

curl -L https://time.is/clock/Moscow
<h1 style="font-family:sans-serif;padding:20px">Please do not scrape our pages! Thanks!</h1>

This is confusing, I didn’t even immediately understand why I only had a black screen and a mouse cursor, found this related issue: #405

Maybe this will be helpfull for someone else.

Btw, this tutorial is too complicated: https://www.raspberrypi.com/tutorials/how-to-use-a-raspberry-pi-in-kiosk-mode/
It can be replaced with only 3 simple steps:

1. Install FullPageOS (can be pre-configured via Imager) on SD card
2. Edit file /boot/fullpageos.txt (insert https://time.is/clock)
3. Launch your PRi

Profit!

Thanks for your contribution!
I would suggest though to change the user agent to a linux machine, since this is a linux machine and that I would like it to show up as one on world statistics.

    Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36

BTW according to here it shows up as x86_64
I can change it or you are welcome to update the PR (will get merged faster)

Regarding your second comment:
I will just point out that when I posted this OS on Raspeberrpy Pi forms 9 years ago this is the reaction I got:

So I am happy the trend is that this is useful. And noways its on the official raspberrypi image :)
Also that guide does not take in to account the screen goes blank after 30 minutes.
