thanks so much for the issue! I can reproduce temporary workaround: adding leading `/` in the `include` solves the issue

```yaml
id: test
namespace: dev

tasks:
    - id: test
      type: io.kestra.plugin.scripts.python.Commands
      namespaceFiles:
        enabled: true
        include:
          - "/test/**"
      commands:
        - ls test/ .
```

Using 'include' fails when injecting namespaceFiles
### Explain the bug

When I wanted to inject the `test` directory in namespaceFiles, I used the `include` keyword according to the documentation, but the `test` directory was not injected successfully as expected.

```
id: test
namespace: test

tasks:
    - id: test
      type: io.kestra.plugin.scripts.python.Commands
      namespaceFiles:
        enabled: true
        include:
          - "test/**"
      commands:
        - ls -R /tmp/kestra-wd
```
