New OpenBSD images (7.4 & 7.5)

[hcartiaux]

New images for OpenBSD 7.4 & 7.5 generated with build_openbsd_qcow2.sh.

The generation command is: ./build_openbsd_qcow2.sh -r '7.5' --image-file 'openbsd-min.qcow2' --size '2' --disklabel 'custom/disklabel.cloud' --sets '-game*.tgz -x*.tgz' --allow_root_ssh 'no' -b

I've also regenerated a new OpenBSD 7.4 image in order to be consistent with the "About" section.

The files have been produced via github actions and are hosted in a github release, the build and test process can be seen here:

• 7.4 - https://github.com/hcartiaux/openbsd-cloud-image/actions/runs/9098913448
• 7.5 - https://github.com/hcartiaux/openbsd-cloud-image/actions/runs/9054992630

Note that a checksum file is also available to verify the integrity of the images.

I've tested the "NoCloud" data source in the github action, and manually using terraform and the libvirt provider.

Feel free to adapt this PR and/or re-host the files elsewhere if you prefer :)
