Label key has been removed

The label key is no longer supported in i3blocks. All blocks using this key in their default configuration should be updated to no longer use it.

Hi @kb100, thanks for the follow up. Note that they can actually print $label, but given the uppercase convention you used in this repo, the idea might be to rename it to LABEL (or eventually use a static block on its left with a full_text if cleaner).
