Generate Typescript connector builder API client code

[lmossman]

Tell us about the problem you're trying to solve

As described in the Tech Spec, the connector builder server API that will back the UI is defined in an OpenAPI specification, so that server and client code can be auto-generated from the API spec.

Describe the solution you’d like

This ticket involves configuring the airbyte-webapp to auto-generate typescript classes from the connector-builder-server OpenAPI spec on build, so that the webapp always has the most up-to-date classes available for the API.

This will look similar to how we generate client classes from the Airbyte API spec:

airbyte/airbyte-webapp/orval.config.ts

Line 5 in 62500af

input: "../airbyte-api/src/main/openapi/config.yaml",

Acceptance Criteria

• Typescript classes are auto-generated in the airbyte-webapp module from the connector-builder-server API spec on build
• Ignore the generated classes, similar to AirbyteApiClient
