Arguments after semicolon (`;`) will not be passed to the program when the parameters are not quoted

**Minimal reproducible example DAG**
```yaml
steps:
  - name: step 1
    command: echo HELLO; WORLD
```

**Expected behavior**
expected: `HELLO; WORLD`
actual: `HELLO`

If the arguments are enclosed with double quotes, this issue does not happen. So it should not be a critical issue.

```yaml
steps:
  - name: step 1
    command: echo "HELLO; WORLD"
```
