CLI: Local dev with cloud only workflow fails

### What is the current behaviour?
Local dev without local dev is currently not possible? Currently ddn connector-link update --add-all-resources, calls the connector schema URL to get the NDC schema and generate the models. However, the cloud connector URL's are not accessible to the public internet and hence this command doesn't succeed.

We cannot track models via the LSP either

### What is the expected behaviour?
CLI should have an option to generate all the models and commands (behaviour of --add-all-resources) from connector-link.hml that's generated during ddn connector build

### How to reproduce the issue?

1. Do a cloud connector build
2. Use the generated cloud connector URL's in the .env files in the connector-link update

### Please provide any traces or logs that could help here.

### Any possible solutions/workarounds you're aware of?

### Keywords

Start with `ddn connector-link update --add-all-resources` and the `connector-link.hml` produced by `ddn connector build`; compare how the command currently obtains the NDC schema with the local artifact. Done means cloud-only local development can generate all models and commands without accessing cloud connector URLs, and the LSP can track those models.
