Description

```python
# [start workflow]
from pydolphinscheduler.core import Workflow
from pydolphinscheduler.core.resource import Resource
from pydolphinscheduler.tasks import Shell

dependence = "dependence.py"
main = "main.py"

with Workflow(
name="multi_resources_example",
# [start create_new_resources]
resource_list=[
Resource(
name=dependence,
content="from datetime import datetime\nnow = datetime.now()",
),
Resource(name=main, content="from dependence import now\nprint(now)"),
],
# [end create_new_resources]
) as workflow:
# [start use_exists_resources]
task_use_resource = Shell(
name="use-resource",
command=f"python {main}",
resource_list=[
dependence,
main,
],
)
# [end use_exists_resources]

workflow.run()
# [end workflow]
```
Change the above usage to the following usage
```python
# [start workflow]
from pydolphinscheduler.core import Workflow
from pydolphinscheduler.core.resource import Resource, LocalResource
from pydolphinscheduler.tasks import Shell

dependence = "dependence.py"
main = "main.py"

with Workflow(
name="multi_resources_example",
) as workflow:
# [start use_exists_resources]
task_use_resource = Shell(
name="use-resource",
command=f"python {main}",
resource_list=[
LocalResource('dependence.py'),
LocalResource('main.py'),
LocalResource('*.py'),
],
)
# [end use_exists_resources]

workflow.run()
# [end workflow]
```

Research direction

Start with the Resource and LocalResource entry points and the Shell resource_list usage shown in the issue. Trace how local resource names and glob patterns are handled when a task is created. Done means local files can be supplied through LocalResource, including '*.py', without defining a Workflow resource_list first.
