[BUG] Make Flytefile and Flytedirectory's copilot local execution work correctly

[Future-Outlier]

Describe the bug

In the unit test below, "{{.inputs.inputs}}", is a wrong syntax, please make /var/inputs work.
(for FlyteFile and FlyteDirectory, we should not use the template's syntax above.
If we use it, the propeller will retrieve the blob type's path, which is not the expected behavior we want.

https://github.com/flyteorg/flytekit/blob/master/tests/flytekit/unit/core/test_local_raw_container.py#L16-L61

Expected behavior

For flyte directory and flyte file,
make /var/inputs work and make "{{.inputs.inputs}}" doesn't.
