Fix TypeScript inclusion in tsconfig.json for cli-v3 init (#1105)

* Fix TypeScript inclusion in tsconfig.json for cli-v3 init

Fixed an issue where TypeScript files were included in the project directory when no include directive was present in tsconfig.json. Previously, the CLI added trigger.config.ts to the inclusion list by default, causing TypeScript compilation errors for other files. The fix ensures that trigger.config.ts is only added to the inclusion list if there's an existing include directive present in tsconfig.json

* Create hot-fishes-retire.md
