Update Ci: remove actions-rs/cargo@v1

As stated in the document of `actions-rs/cargo@v1`, this action is not required usually, and we can use `cargo` command in run directly instead. For example, replace

```yaml
- uses: actions-rs/cargo@v1
  with:
    command: fmt
    args: --all -- --check
```

with

```yaml
- run: cargo fmt --all -- check
```
