[feat] Auto create not exist environment config when submit workflow

```python
environment = Environment(name="python-numpy", config="export PYTHON_HOME=/xxx/xxx/python3")
task = Python(name="123", definition="import numpy as np", environment_name=environment)
```
if `python-numpy` exist, update the environment, if not create a new environment.

The issue names the Environment and Python workflow objects but no file or test. Trace workflow submission from the Environment/Python construction shown, then verify the existing-environment update and missing-environment creation paths; done means both cases submit successfully with the requested configuration.
