chore(docker): update image metadata (aka the org.opencontainers.image.* labels)
This commit involves updating the source repo URL to reflect where the image builds happens,
as well as to mention @recaptime-dev (@recaptime.dev in the Atmosphere/Tangled) as the
vendor/distributor of the image, among other things (including updating the docs link to point to
the new docs site).
