build: stop publishing executables in GitHub (focus is container images)

primary motivation for this is broken publish step after bumping buildkit-golang
which now empty dummy dotfile in `rel/` directory. for background see:
function61/buildkit-golang@525a63d

if we'd want to fix this, we'd upload only non-dotfiles

but I see that as lacking ROI as the word should move to container image-based distribution for
even things like executables they want to take out of the container anyway
