Updated Terraform section with the latest provider.

This updates the section with an example of a simple Libvirt VM automation using the latest version of the Terraform provider.

How to use

Check the text and the example. The example should be executable with minimal setup ("default" network and "default" pool).

Testing done

This is documentation only changes.

• Changelog entries added in the respective changelog/ directory (user-facing change, bug fix, security fix, update)
• Inspected CI output for image differences: /boot and /usr size, packages, list files for any missing binaries, kernel modules, config files, kernel modules, etc.

Closes: flatcar/Flatcar#1996

Thanks a lot, that's great to see that. I added two suggestions, feel free to force push them in the same commit.

Might I ask you to signoff your commit as well? As part of a CNCF project, all commits must be signed-off.

@atarutin thanks for signing off the commits. That looks good now. One last thing, following this suggestion: #531 (comment) - can you update the Terraform snippet to move the variables outside the resource block (and remove the 3 dots ...) ? https://github.com/atarutin/flatcar-website/blob/308c00d3b87c16efcfac3a11fba637f5eba016c6/content/docs/latest/installing/vms/libvirt.md?plain=1#L275-L298
Because now the snippet is now usable. :)

can do. though it's going to have to wait until later or maybe even until tomorrow.
