Subject: [PATCH] Add B300 (sm_103) variants to docker-publish workflow

Add an x86_sm103 docker context targeting CUDA architecture 103
(B300 / Blackwell Ultra, CC 10.3) and double- and single-precision
matrix entries that build on the higherordermethods/selfish
latest-x86-cuda130-sm103 base image.
