OpenAPT fails to load schema due to deprecated call to yaml.load without Loader argument

[spirent-leetaylor]

When working on Debian 12/bookworm with python3.11 I see the following error:

Traceback (most recent call last):
File "/home/ltaylor/.local/bin/openapt", line 8, in
sys.exit(main())
^^^^^^
File "/home/ltaylor/.local/lib/python3.11/site-packages/allocloud/openapt/main.py", line 64, in main
run(**args)
File "/home/ltaylor/.local/lib/python3.11/site-packages/allocloud/openapt/init.py", line 37, in run
_schema = yaml.load(f)
^^^^^^^^^^^^
TypeError: load() missing 1 required positional argument: 'Loader'
