Suppress the confirmed G703 diagnostic for the operator-selected file path.

The configured Go lint command reports G703 for this os.ReadFile call. The path is intentionally supplied through the environment, so add a targeted suppression with a justification.

Suggested fix 
-		content, err := os.ReadFile(filepath.Clean(value))
+		content, err := os.ReadFile(filepath.Clean(value)) //nolint:gosec // Path is operator-supplied via environment.

Address the G703 finding at the environment-file os.ReadFile call by validating
the operator-supplied path before reading it; keep the existing
environment-variable selection flow unchanged.
