OIIO is missing in VFX CY2024 and VFX CY2025 CI builds.

Looks like containers for CY2024 and CY2025 don't have OIIO in them thus the CI builds that are set to exercise OIIO build without OIIO.

Log snippet from the "**Linux VFX CY2024 \"**, Configure step:
```
-- Checking if the OpenImageIO found is built with OpenEXR 3+...
-- Could not find OpenImageIO header to evaluate the OpenEXR version.
-- Please provide the OpenImageIO_DIR variable.
-- If your OpenImageIO's files are located in different root directory, please provide the OpenImageIO_ROOT where the include files are located.
```

Older containers 2022 and 2023 do have OIIO, and CI builds use them as intended.

Inspect the CI container definitions for CY2024 and CY2025 and compare them with the working 2022 and 2023 containers. Run the affected VFX configure step and verify that OpenImageIO is installed and discovered when OIIO is enabled.
