Some CONFIG_OVERWRITE_JSON system parameters are missing from the documentation

[Lunadoz]

Hello,

The official Harbor documentation for configuring system settings via the CONFIG_OVERWRITE_JSON environment variable is incomplete.
Several system configuration keys are available through the API but are not documented for CONFIG_OVERWRITE_JSON.

While inspecting /api/v2.0/configurations and testing CONFIG_OVERWRITE_JSON in Harbor 2.14.0, I confirmed that the following keys work correctly, but are missing from the documentation: https://goharbor.io/docs/2.14.0/install-config/configure-system-settings-cli/#harbor-configuration-items
notification_enable
quota_per_project_enable
storage_per_project
session_timeout
disabled_audit_log_event_types

These settings are not listed in the “Configuration Items” section of the documentation.
Quota-related fields are especially important, as they allow configuring the default project quota, but admins currently have no way to discover them unless inspecting the API (or web interface).
This creates an inconsistency between Harbor’s documented configuration capabilities and its actual behavior.

Environment:

• Harbor version: 2.14.0
• Installation type: docker-compose
• Behavior reproduced consistently

Thanks for your work, I would like improve this documentation would make Harbor significantly easier to configure declaratively and automate in IaC workflows.
