Support editing local directory for Cloud Run Kubernetes

(Please ensure you are running the latest version of Cloud Code for IntelliJ with _Help > Check for Updates_)
- Cloud Code for IntelliJ version: 22.8.1-221
- Google Cloud SDK version: 398.0.0
- OS: Windows 11 10.0

**What did you do?**

Create a skaffold.yaml file and add a new Cloud Code: Kubernetes Run/Debug Configuration. Click the Debug button to build, deploy and debug the code. The plug-in recognizes that I have several artifacts to debug, but assumes that the local path is the same as the build context. This is not the case, because the Dockerfile needs to pull together multiple Python modules into a single area to run, so the Dockerfile context needs to be a higher level directory.

**What did you expect to see?**

The modal that comes up to map the local directory to the remote directory should allow the local directory to be customized, not just the remote directory.

**What did you see instead?**

The model has a read-only field for the local directory.
