Correct Helm flag from --set-string to --set in docs and CLI examples

[brooke-hamilton]

Description

Replaces --set-string with --set for global.imagePullSecrets in documentation and CLI command examples. The --set-string flag is unnecessary here because the values being set are already strings, and using --set is the standard and correct approach for these Helm chart values.
