@xmfcx Thank you for your pointing out my mistake here. Could I ask you to review this PR?

[xmfcx]

Sorry @badai-nguyen I should have tagged you as well on this PR from yesterday:

• https://github.com/autowarefoundation/autoware/pull/4675

I've replaced this readme part with a new playbook that only downloads and extracts these files.

Could you try and if it works, approve?
