Add coverage to flux_led to ensure a user flow can replace an ignored entry (#142103)

* Ensure a flux_led user flow can replace an ignored entry

Allow ignored devices to be selected in the user step and replace the ignored entry.

Same as #137056 and #137052 but for flux_led

* works as-is was a problem with core.config_entries
