[BUG] bulk-export errors with "[NotSupported] Only supported for Lakehouse/Files"

Bug Description

When attempting to do a bulk export of items from any workspace or folder I get the error

"x bulk-export: [NotSupported] Only supported for Lakehouse/Files"

The error is actually regarding the output filepath parameter

fab bulk-export <workspace>/<folder> -o ./ --recursive

.. fails

fab bulk-export <workspace>/<folder> -o ./temp --recursive

.. succeeds.

fabric-cli version

1.7.0

Python version

Python 3.12.0

Operating System

Windows

CLI Mode

Command line mode

Authentication Method

Interactive browser login

Steps to Reproduce

1. Go to a local temporary folder.
2. Command

fab bulk-export / -o ./ --recursive

(redacted)

Expected Behavior

Users would reasonably assume the path resolution should work for any valid filesystem path

Actual Behavior

Cli immediately errors with
"x bulk-export: [NotSupported] Only supported for Lakehouse/Files"

Bulk export aborts with no items exported.

Additional Context

No response

Possible Solution

Either the path resolver needs updating to allow os-aware filepath formats, or the docs need to be more explicit about the path requirements

Start by reproducing fab bulk-export <workspace>/<folder> -o ./ --recursive and compare it with the successful -o ./temp command. Trace the bulk-export output path validation or documentation for filesystem path requirements; done means a valid current-directory path no longer produces the Lakehouse/Files error and recursive export completes.
