arcdata extension 1.5.27 fails to install on Azure CLI 2.82.0 (Python 3.13) due to regex build / setuptools.build_meta error

### Describe the bug

# Description

Installing the arcdata Azure CLI extension fails on Azure CLI 2.82.0, which bundles Python 3.13, due to a dependency build failure when installing regex==2023.10.3.

The extension installation attempts to build regex from source (sdist), and the pip build isolation environment fails with:

```
pip._vendor.pyproject_hooks._impl.BackendUnavailable:
Cannot import 'setuptools.build_meta'
```

This appears to be a compatibility issue between:

- arcdata 1.5.27 (current/latest version in the extension index),
- pinned dependency regex==2023.10.3,
- and Azure CLI’s embedded Python 3.13.

# Observed Behavior

During extension installation, pip attempts to install dependencies and falls back to building regex==2023.10.3 from source:

```
Collecting regex==2023.10.3
Downloading regex-2023.10.3.tar.gz
Installing build dependencies: done
Getting requirements to build wheel: done
BackendUnavailable: Cannot import 'setuptools.build_meta'
```

The failure occurs inside pip’s PEP517 isolated build environment, even though setuptools.build_meta is importable in the base Azure CLI Python environment.

### Related command

# Steps to Reproduce

1. Install Azure CLI 2.82.0 on Windows
2. Run:
```powershell
az extension add -n arcdata --debug
```
3. Observe failure during dependency installation

### Errors

```powershell
az extension add --name arcdata
An error occurred. Pip failed with status code 2. Use --debug for more information.
```

### Issue script & Debug output

```powershell
az extension add -n arcdata --debug
```

### Expected behavior

- az extension add -n arcdata succeeds on supported Azure CLI versions
- Or, the extension is updated to:
- use dependency versions compatible with Python 3.13, or
- avoid source builds on newer Python versions

### Environment Summary

- Azure CLI version: 2.82.0
- Python version (bundled): 3.13.9
- OS: Windows 11
- Installation method: Azure CLI MSI
- Extension index: https://aka.ms/azure-cli-extension-index-v1

```
az --version
azure-cli 2.82.0
Python (Windows) 3.13.9
```

### Additional context

# Additional Notes / Analysis

- The official extension index currently only exposes arcdata 1.5.27
- There is no newer version available that relaxes or updates the regex dependency
- Installing Azure CLI LTS (Python 3.12) avoids the issue, suggesting a Python 3.13 compatibility gap
- This blocks usage of arcdata on current Azure CLI releases unless users downgrade CLI versions or manually intervene
