Bind "prediction.py" to /prediction

Description

README and QuickStart are referring to /prediction, not /predictions

https://github.com/opendatahub-io/odh-s2i-project-simple/blob/8a05dc1f1fa707b8b6a4d3476e1efa7e5f7ee3fb/README.md?plain=1#L106 https://github.com/opendatahub-io/odh-manifests/blob/78085dd5e4e58b1b9ce66705894cbb0c0bbf1f8c/odh-dashboard/apps/jupyter/deploy-python-model-quickstart.yaml#L72

wsgi.py:@application.route('/predictions', methods=['POST'])

indicates that /predictions is used everywhere except in the README.md. So I'd just propose to fix that.

I've filed https://github.com/opendatahub-io/odh-s2i-project-simple/pull/10 now as the alternative fix.
