feat: Update container base image from AL2 to AL2023

Update all container base images from Amazon Linux 2 to AL2023:
- mp_builder stage: amazonlinux:2 -> amazonlinux:2023
- Package manager: yum -> dnf (AL2023 uses DNF)
- Go builder: golang:1.26.2 -> golang:1.26.2-al23
- Runtime: eks-distro-minimal-base-csi:latest -> latest-al23
- Dockerfile.local: golang:1.26.2 -> golang:1.26.2-al23

Also removes the outdated comment about building on AL2 for old libc,
as AL2023 provides the necessary glibc compatibility.
