Pull request overview

This PR refreshes the azure-mgmt-botservice management-plane package by regenerating it from TypeSpec (spec commit a7bdbe7, API version 2023-09-15-preview), releasing it as a beta major version bump (2.0.0 → 3.0.0b1). The migration renames the public client from AzureBotService to AzureBotServiceMgmtClient, moves generated operations into consolidated _operations.py modules, adds new Network Security Perimeter operations, and modernizes packaging (drops setup.py/sdk_packaging.toml/_meta.json in favor of pyproject.toml + _metadata.json).

Changes:

• Regenerated client/config/operations from TypeSpec; renamed client to AzureBotServiceMgmtClient and raised the minimum Python to 3.10.
• Migrated packaging metadata into pyproject.toml, updated README.md, MANIFEST.in, tsp-location.yaml, and refreshed generated samples/tests.
• Documented the API surface changes and breaking changes in CHANGELOG.md for 3.0.0b1.

I verified the mgmt review rules: version consistency (_version.py == CHANGELOG 3.0.0b1), release date not in the future, preview stability flags (is_stable=false + Beta classifier), client name consistency across _client.py/README/pyproject title, and client __init__ order credential, subscription_id, base_url. All pass. No actionable defects were found within the changed regions of reviewable (non-generated) files.
