[FEATURE]: Add diet pi

[godalming123]

I've never used diet pi, and was wondering if there is a reason that it is not available in raspberry pi imager before I install it. If not, then I think that it should be added to raspberry pi imager.

Version

1.9.0

[lurch]

It's up to the Diet Pi maintainers to request inclusion in https://downloads.raspberrypi.com/os_list_imagingutility_v4.json and there's some Google-form that they have to fill out to do that. I can never remember that URL, but hopefully @tdewey-rpi will be able to provide it... 😉

Apparently we are talking about this link: https://forms.gle/X7HpED5fYcjW1k8c7

Her mention was noticed here: https://github.com/raspberrypi/rpi-imager/issues/941#issuecomment-2428925180

I'll add that inclusion in the available images has already been discussed here: https://github.com/MichaIng/DietPi/issues/5364

Tried to renew the discussion.

We were digging into it and have a JSON which seems to work and which we can host/maintain/update on our server.

Here the full example for testing, being aware that only the os_list part is needed: https://github.com/MichaIng/DietPi/pull/7450/files

DietPi v9.13 has been released, which makes the password change mandatory, being one of the factors for adding a distro to the Raspberry Pi Imager. This also applies retrospectively: during the DietPi update (which runs automatically when booting also older images the first time), admins are prompted to change the password, if the default is currently applied.

The JSON is hosted at: https://dietpi.com/downloads/images/rpi-imager.json And will be updated whenever we update our images, which will happen either later tonight or tomorrow.

Let me know if anything is missing.

@tdewey-rpi Sorry for the ping. Just avoiding to split discussion across another duplicate request. As mentioned above, password change is now mandatory in DietPi, JSON hosted and updated automatically, Google form was filled before that change, Let me know if something is missing.

I already wanted to open a PR, but as far as I can see, the Imager fetches the OS list from https://downloads.raspberrypi.com/os_list_imagingutility_v4.json, so no source code change required.
