chore: remove INSTALL_BOTO3 and INSTALL_ACP build args

[simonrosenberg]

Summary

• Remove ARG INSTALL_BOTO3 from Dockerfile — always install the boto3 extra
• Remove ARG INSTALL_ACP from Dockerfile — always install ACP servers
• Clean up stale INSTALL_ACP example in BuildOptions.extra_build_args description

All images now unconditionally include boto3 and ACP deps. The conditional ARGs added unnecessary complexity for negligible size savings.

Closes #2569

Test plan

• CI builds the Docker image successfully without the removed ARGs
• Benchmark images include boto3 and ACP deps as expected

About Multi-Architecture Support

• Each variant tag (e.g., 16ad7b5-python) is a multi-arch manifest supporting both amd64 and arm64
• Docker automatically pulls the correct architecture for your platform
• Individual architecture tags (e.g., 16ad7b5-python-amd64) are also available if needed

🟢 Good taste - Clean simplification that removes unnecessary conditional complexity. The defaults were already true, so this just eliminates the option to disable boto3/ACP, making builds more predictable. LGTM!
