Masahiro Hiramori 021547febf [CI] Upgrade Python to 3.10 in CI (#18647) ...

Part of #18682

Python 3.9 is EoL in 2025-10, so it's a good time to move to 3.10. Also,
upgrade other dependencies.

- #17425

## Personal notes for upgrade

### Docker Base Images and Ubuntu Versions

| Dockerfile | Base Image | Ubuntu Version |
|------------|------------|----------------|
| Dockerfile.ci_arm | `ubuntu:22.04` | **Ubuntu 22.04** |
| Dockerfile.ci_cpu | `ubuntu:22.04` | **Ubuntu 22.04** |
| Dockerfile.ci_gpu | `nvidia/cuda:12.4.1-cudnn-devel-ubuntu22.04` |
**Ubuntu 22.04** |
| Dockerfile.ci_lint | `ubuntu:22.04` | **Ubuntu 22.04** |
| Dockerfile.ci_wasm | `ubuntu:22.04` | **Ubuntu 22.04** |

Ubuntu 20.04 LTS is [EoL on
2025/5](https://ubuntu.com/about/release-cycle) so we'll deprecate
ubuntu 20.04 images
