[WebPubSubClient] Convert azure-messaging-webpubsubclient package from setup.py to pyproject.toml

[Copilot]

This PR converts the azure-messaging-webpubsubclient package from using setup.py to the modern pyproject.toml configuration format, following the Azure SDK Python guidelines and the pattern established by other Azure SDK packages.

Changes Made

• Replaced setup.py with complete pyproject.toml: Migrated all package metadata, dependencies, and build configuration from the legacy setup.py to a comprehensive pyproject.toml file
• Dynamic version configuration: Set up dynamic version loading from azure.messaging.webpubsubclient._version.VERSION
• Build system setup: Added proper build-system configuration with setuptools>=77.0.3 and wheel
• Package discovery: Configured package finding with appropriate exclusions for tests*, azure, and azure.messaging namespace packages
• Dependencies migration: Moved all runtime dependencies and optional dependencies (aio extra) to the new format
• py.typed configuration: Properly configured the py.typed file location for type hint support

Key Requirements Addressed

✅ Dynamic version file path: Correctly points to azure.messaging.webpubsubclient._version.VERSION
✅ Python version requirement: Maintains >=3.8 compatibility
✅ Repository URL: Set to "https://github.com/Azure/azure-sdk-for-python.git"
✅ py.typed setup: Configured as pytyped = ["py.typed"]

The conversion follows the same pattern used by azure-eventhub and other modernized Azure SDK packages. All metadata, dependencies, and build configuration have been preserved while moving to the standardized pyproject.toml format.

Fixes #42461.

Firewall rules blocked me from connecting to one or more addresses

I tried to connect to the following addresses, but was blocked by firewall rules:

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
