Update/Fix CI workflow

- Fixed cargo fmt
- Updated MSRV to v1.57.0, which is needed for `base64` v0.20
- Updated all actions to the latest versions. (Solves Annotation warnings)
- Replaced actions-rs with dtolnay actions or simple run's.
  actions-rs is not supported anymore, and also causes warnings.
- Use Ubuntu 20.04 for `linux / nightly`.
  The reason is that Ubuntu 22.04 uses OpenSSL v3, this currently is not compatible with hyper-tls it looks like. I also tried to update the `openssl-sys` crate but that doesn't solve the compile issue. Using a Ubuntu version that still has OpenSSL v1.1.1 resolves the CI for now.
