[TCE-1171] export command cause error to be swallowed

[jackie-linz]

see https://www.shellcheck.net/wiki/SC2155

so this command

        export PREVIOUS_VERSION=$(git-version \
            --previous-version \
            --release-branch "${{ inputs.release-branch }}" \
            --dev-branch "${{ inputs.dev-branch }}" \
            --minor-identifier="${{ inputs.minor-identifier }}" \
            --major-identifier="${{ inputs.major-identifier }}" \
            --version-prefix "${{ inputs.prefix }}")

means that the step still succeeds even if the git-version errors for whatever reason (in our case we forgot actions/checkout step, which caused git-version to fail with [ERROR] Command git describe --tags failed. (Exception)).

In fact in this action there is no need for export at all, as it's only used in subsequent bash commands so it would still work
