setupShell would update the shell stored on the `Step` object to a new interpolated value. If the expression evaluation was interpolated with reference to a matrix input to the job, that shell can be written to multiple *different* values for each RunContext, resulting in a data race that causes incorrect shells to be used for each concurrent matrix run.
