Update screenshots for PF4-ish reskinning

[garrett]

When cockpit-project/cockpit#11987 lands, we probably want new screenshots on the website.

To everyone: Feel free to upload screenshots here on the issue. I'll add optimized versions of them on a PR.

Thanks!

I looked what we currently have and try to recreate them. I havn't done the one from dashboard as I have only one machine set up. If anyone else would do that that would be great, otherwise I can setup some machines. And also instead of docker I took screenshot of podman containers as it seems to be now the trend :)

I did a Dashboard screenshot with three machines and three different OSes:

Annoyingly this has a scrollbar, even though there's no content below the server list. That's something we should fix, too :-)

Thanks for the screenshots! However, there are some issues.

@marusak: Your screenshots are using the wrong fonts and have "localhost.localdomain" as the hostname. We cannot use these for that reason. There are also incorrect widgets in some for odd reasons.

@martinpitt: Your screenshot is too wide.

We need to update the screenshots according to the screenshot guidelines @ #183

We'll need to update the screenshots with the dark nav and search... and make sure they're in accordance with #183

Resolved in #373.
