feat: use more informative bk labels

Replace emoji driven labels in favour of
simpler labels with more information in them. These labels
will be used as names for saved BK results, so instead of
simple UUID like "019a53c5-629b-40b1-86f0-a6d45e07aaf9"
it will look like "m6g.metal-al2023-linux_6.1-virtio-block-sync".
