Github action that runs npm run download-openapi and rebuilds the project on cron

Here's an example of a Github action cron that runs daily https://github.com/seamapi/roles/blob/main/.github/workflows/sync.yml

@seveibar, do we want to change how openapi spec is generated and worked with? Currently it's installed as a dependency and generated in get-api-definitions.ts. Should I create a script that generates an openapi spec and will replace the dependency?
