| /* | ||
| This utility can be used to generate a new release name in the format: | ||
| <cat breed> <robot name> | ||
| to be used for a Tekton Pipelines release. | ||
| It looks for cat breeds from CatAPIURL and it parses robot names out | ||
| of Wikipedia WikiURL. It filters names that have been used already, | ||
| based on the GitHub API GitHubReleasesURL | ||
| To use, run: | ||
| go run release_names.go | ||
| Example output: | ||
| { | ||
| "release_name": "California Spangled Clank", | ||
| "cat_breed_url": "https://en.wikipedia.org/wiki/California_Spangled", | ||
| "robot_url": "https://en.wikipedia.org/wiki/Clank" | ||
