How Has This Been Tested?

west build -p -b b_u585i_iot02a ocre-runtime/src/samples/supervisor/zephyr/ -- "-DOCRE_PRELOADED_IMAGES=ocre-sdk/generic/big-sample/build/big-sample.wasm" "-DOCRE_SDK_PRELOADED_IMAGES=webserver.wasm;filesystem.wasm;hello-world.wasm"
west flash --hex-file=build/zephyr/merged.hex

fix(supervisor): boards(b_u585i_iot02a): fix external flash syntax
1f0a126 
The syntax which was used is outdated. The commit mirrors the configs which will be delivered in zephyr v.4.4.
When that happens, this can be reduced to only container storage_partition node.
