Fixed requiring positional arguments for API URL parameters (#878)

## Changes
Some commands such as update commands have an argument in their url, for
example in pipeline we have `PUT pipelines/<id>` to update the pipeline.

Such parameters must be required and respected even if `--json` flag
with the payload passed.

Note: this depends on these PRs in Go SDK:
 https://github.com/databricks/databricks-sdk-go/pull/660
https://github.com/databricks/databricks-sdk-go/pull/661

## Tests
Manually running `databricks pipelines update`
