[TCE-1171] export command cause error to be swallowed #97
Description
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
