Updated settings variable as per the defaults in the same file

[Ballard-dev]

Updated settings variable as per the defaults in the same file which would cause a KeyError on line 148 in event_task_to_version_status.py when not setup

Changelog Description

From:

    asset_types_to_skip: list[str] = SettingsField(
        title="Skip on Asset types (short)",
        default_factory=list,
    )

To:

    asset_types_filter: list[str] = SettingsField(
        title="Skip on Asset types (short)",
        default_factory=list,
    )

Additional info

The defaults DEFAULT_SERVICE_HANDLERS_SETTINGS dictate that the modified variable name should now be correct.

Testing notes:

1. Configure addon
2. Sync
3. Encounter KeyError
