fix: gitlab publish being broken due to bash weirdness

[corang]

Description

When you have escaped double quotes in a bash variable bash does some weird single quote things that the command actually ran looks like this

--set 'FLAVOR="upstream"'

which breaks our stuff
Fix is to switch to a bash array for keeping track of everything:

        ARGS=(
          --set FLAVOR="$[[ inputs.flavor ]]"
          --set VERSION="$(uds-releaser show $[[ inputs.flavor ]] --version-only)"
        )

          ARGS+=(--set TARGET_REPO="$[[ inputs.target-repo ]]")
