Use docker/metadata-action to make sure all opencontainer labels are set

[halkeye]

I use renovate to make sure my deployed apps are up to date. (see) and according to the documentation if the source docker label is set, it'll actually pull in the release notes.

I checked the latest release, and it doesn't seem to have the labels (or any labels) set, so using the pre-existing github action should populate all the nice metadata.

regctl image config --format '{{ jsonPretty .Config.Labels }}' ghcr.io/plankanban/planka
