GetManagerNicInventory (#49961)

* Add GetManagerNicInventory command for Manager category, and tweak redfish_utils' get_nic_inventory to accommodate manager nic interfaces

* Remove get_manager_nic_inventory, since it is unnecessary while using get_manager in get_nic_inventory

* Rework get_nic_inventory() to take a resource_type as a string, which will be just the category parameter from redfish_facts, making it clearer

* remove extraneous blank line to conform with pep8

* Add GetManagerNicInventory example task to EXAMPLES docstring

lib/ansible/modules/remote_management/redfish/redfish_facts.py
