Fix error swallowing in workbenches component status update

[coderabbitai]

Problem

In internal/controller/components/workbenches/workbenches.go at lines 143-145, the code incorrectly swallows client.Get errors by returning nil instead of propagating them:

if err := rr.Client.Get(ctx, client.ObjectKeyFromObject(&c), &c); err != nil && !k8serr.IsNotFound(err) {
    return cs, nil  // <- This hides real errors
}

This masks genuine failures and makes debugging difficult in production environments.

Suggested Fix

if err := rr.Client.Get(ctx, client.ObjectKeyFromObject(&c), &c); err != nil && !k8serr.IsNotFound(err) {
    return cs, err  // <- Properly bubble up the error
}

@lburgazzoli not sure why this return nil on all components except codeflare.
should that be corrected to "cs, err" as issue suggested on all components?
