[FEATURE] (type-safe-api) only require OpenApi Generator when API changes

### Describe the feature

Enable generated type-safe-api code to optionally be committed to the repo and only run OpenAPI Generator when the api spec is modified.

### Use Case

I've heard developers say they are hesitant to adopt type-safe-api because it adds a dependency on the JDK and maven and that could be an issue for their customers. By committing the generated code, only developers who modify the API spec will need those dependencies.

### Environment details (OS name and version, etc.)

Start by locating the type-safe-api generation entry points, the API spec, and how OpenAPI Generator is currently invoked. Determine how generated TypeScript, Java, and Python code can be committed and how changes to the API spec trigger generation; done means unchanged specs avoid requiring the JDK and Maven while generated code stays up to date.
