[Bug]: FS - Shell Command doesn't handle ".." path

### What happened?

Shell Command node failed to resolve a valid path containing `..`.

### What was the expected functionality?

Valid shell path woudl be handled as in any normal shell.
The same command works with default WIndows shell (not PowerShell or some such).

### Describe your environment

Windows 11, default command prompt
`cp` comes from Git Bash installation.

### Relevant log output

_No response_

### Relevant screenshots


### Code of Conduct

Start at the Shell Command node entry point and reproduce the reported Windows 11 case with a valid path containing `..`, using the default command prompt and `cp` from Git Bash. Trace how that path is handled and verify the command succeeds as it does in a normal shell.
