a little typo in the documentation how to run CLI with help option $ python3 oci_capacity_reporter_gui.py -help

hello folks
just my observation that the proposed way to call for help (with single dash):

python3 oci_capacity_reporter_gui.py -help

does not work as expected and causes an error:

> python oci_capacity_reporter_gui.py -help
oci_capacity_reporter_gui.py: error: argument -h/--help: ignored explicit argument 'elp'

meanwhile the way how it usualy done in Linux (double -) is okay:

> python oci_capacity_reporter_gui.py --help
options:
   -h, --help         show this help message and exit
   -c CONFIG_FILE     OCI CLI Config file
   -t CONFIG_PROFILE  Config Profile inside the config file
   -p PROXY           Set Proxy (i.e. www-proxy-server.com:80)
   -ip                Use Instance Principals for Authentication
   -is                Use Config and Security Token         

the affected doc page is the following:
https://github.com/oracle/oci-python-sdk/tree/master/examples/oci_capacity_reporter

Open the affected documentation in the examples/oci_capacity_reporter page and locate the command showing the help option. Change the documented single-dash form to the working double-dash form, then verify it matches the displayed --help output.
