fix: remove duplicate NOTICE file under bin/single-node

[Ma77Ball]

What changes were proposed in this PR?

• Removed the duplicate NOTICE file under bin/single-node/, which was identical to the project root NOTICE, to avoid the two-copy drift problem.
• Updated .github/workflows/create-release-candidate.yml so the Docker Compose release bundle still includes a NOTICE, now sourced from the root copy (added NOTICE to the git archive paths and repointed the cp).

Any related issues, documentation, or discussions?

Closes: #5296

How was this PR tested?

• Verified the root NOTICE and removed bin/single-node/NOTICE were byte-for-byte identical before deletion.
• Grepped the repo to confirm the release workflow was the only reference, and updated it so the bundle copy still resolves.
