Breaking change: refactor struct steps

This PR includes a breaking change in which struct steps { std::vector<step> steps; }; has just been replaced with std::vector<step> steps where used. This is a breaking change but generally will look like replacing instances of steps.steps with just steps or return {steps} being replaced with return steps. See the diff from #411 for details: https://github.com/viamrobotics/viam-cpp-sdk/pull/411/files
