@youtalk @oguzkaganozt these should be updated too:

• https://github.com/autowarefoundation/autoware.universe/blob/7bebb1a69f6e703bdf04bad08e525487c0573a0a/.github/workflows/build-and-test.yaml#L24
• https://github.com/autowarefoundation/autoware.universe/blob/7bebb1a69f6e703bdf04bad08e525487c0573a0a/.github/workflows/build-and-test-differential.yaml#L31

And their arm64 counterparts. Please keep in mind the universe CI heavily depends on these docker images.
