App metadata behavior is mispelled in metadata.yaml for ptp-notification-app

[Cole Walker]

Brief Description
During review of app metadata.yaml it was observed that ptp-notification has 'behaviour' in metadata.yaml instead of 'behavior'. This is probably causing the app to omit 'platform_managed_app' option.

Severity
Minor

Steps to Reproduce
list="ptp-notification-armada-app/stx-ptp-notification-helm/stx-ptp-notification-helm/files/metadata.yaml"

grep "behaviour" $list

Expected Behavior
The spelling should be the expected spelling as presented in config repo files:

    sysinv/sysinv/sysinv/sysinv/common/constants.py
    sysinv/sysinv/sysinv/sysinv/common/app_metadata.py

Actual Behavior
Mispelled.

Reproducibility
100%
