[Batch] Beta Data Plane SDK 15.1.0b1 (replacing 15.0.0b3)

[cRui861]

Description

Re-release of the latest beta with changes in this PR: #42790

Version 15.0.0b3 is yanked from PyPI.

The 15.0.0b3 release was incompatible with the current changes in the Az CLI. Since the CLI was using ~= for versioning, any patch version will be picked up from PyPI. The CLI is updated to be pinned to the latest compatible version of the Python SDK beta (PR: Azure/azure-cli#32279). By updating the minor version to 15.1.0b1, we will not hit this conflict.

If an SDK is being regenerated based on a new API spec, a link to the pull request containing these API spec changes should be included above.

Pull Request Overview

This PR updates the Azure Batch SDK version from 15.0.0b3 to 15.1.0b1 to resolve a compatibility issue with Azure CLI. The previous beta version (15.0.0b3) conflicted with Azure CLI's ~= version constraint, which would have automatically picked up patch versions. By bumping the minor version, the PR ensures the CLI can remain pinned to a compatible version while this new beta is released separately.

Key Changes:

• Version number updated from 15.0.0b3 to 15.1.0b1
• CHANGELOG entry updated to reflect the new version number

Why are we releasing a new version with no changes?

Ah, I see now that we yanked 15.0.0b3 and this is re-releasing those changes under a minor version bump.
