* Resolve a JSON schema shipped by the `@github/copilot` CLI package. * * The CLI package layout changed in 1.0.64-1: the umbrella `@github/copilot` * package became a thin loader and its bundled assets (including the JSON * schemas) moved into the platform-specific packages installed as optiona

(fileName: string)

 * first (older versions) and then whichever platform package is present.
