chore: Update Go module paths from kubeflow/kubeflow to kubeflow/notebooks

[asaadbalum]

This PR updates all Go module paths from github.com/kubeflow/kubeflow to github.com/kubeflow/notebooks as part of the repository migration.

Changes Made

1. Updated Module Declarations (3 files)

• components/notebook-controller/go.mod
• components/tensorboard-controller/go.mod
• components/pvcviewer-controller/go.mod

Changed module paths from:

module github.com/kubeflow/kubeflow/components/<component>

to:

module github.com/kubeflow/notebooks/components/<component>

2. Updated Import Statements (19 Go source files)

All internal import statements now reference github.com/kubeflow/notebooks to match the new module declarations.

This includes updating imports for the local reconcilehelper (which was moved into each controller in PR #702).

Files updated:

• components/notebook-controller/main.go and controllers
• components/notebook-controller/api/v1/*.go and v1alpha1/*.go
• components/tensorboard-controller/main.go and controllers
• components/pvcviewer-controller/main.go and controllers

Testing

✅ All components compile successfully

cd components/notebook-controller && go build     # ✅ Pass
cd components/tensorboard-controller && go build  # ✅ Pass
cd components/pvcviewer-controller && go build    # ✅ Pass

Files Changed

• 3 go.mod files
• 19 *.go source files

Acceptance Criteria from #699

• All go.mod files reference kubeflow/notebooks instead of kubeflow/kubeflow
• All components compile successfully
• CI pipelines remain green (will be verified after PR)

Closes #699

we will want to rebase this after #702 is merged.

In general - I am comfortable with the changes included in this PR. I am just holding off on the lgtm until after we rebase this once #702 is merged so the CI workflows can do their magic .
