4.x helidon.bat does not propagate exit codes

## Description

CLI execution errors are not propagate on windows when using `helidon.bat` from the generic distribution.

### Steps to reproduce

```shell
C:\>helidon.bat xyz
error: 'xyz' is not a valid command.
See 'helidon --help' for more information

C:\>echo %ERRORLEVEL%
0
```

This will need to be backported against 3.x, as the current release of the cli is 3.0.6.
