Bifrost documentation need to be updated with correct path to inventory files

[sayantani]

Path to inventories to enroll and deploy hardware in Bifrost container is not correct. It leads to the following error:

ERROR! The file inventory/bifrost_inventory.py is marked as executable, but failed to execute correctly. If this is not supposed to be an executable script, correct this with `chmod -x inventory/bifrost_inventory.py`.
Inventory script (inventory/bifrost_inventory.py) had an execution error:
inventory/bifrost_inventory.py:18: Error parsing host definition 'DOCUMENTATION = '''': No closing quotation

Documentation needs to be updated.

Turns out there were a few other changes required for the manual procedure to work.
