While GitHub Actions is a popular choice for writing and running CI/CD pipelines, especially for open source projects hosted on GitHub, it lacks specific quality of life features found in other CI/CD environments. If search is an array, this function returns true if the item is an element in the array. If you generate a value in one step of a job, you can use the value in subsequent steps of the same job by assigning the value to an existing or new environment variable and then writing this to the GITHUB_ENV environment file.
