deps: update outdated packages and fix Dependabot configuration

[joshsmithxrm]

Summary

• Updated Microsoft.PowerPlatform.Dataverse.Client from 1.1.* to 1.2.* (includes CVE-2022-26907 fix)
• Updated test infrastructure: Microsoft.NET.Test.Sdk 18.0.1, xunit 2.9.3, xunit.runner.visualstudio 3.0.2
• Fixed Dependabot configuration to properly detect floating version updates

Root Cause Analysis: Why Dependabot Missed These

Primary Issue: Floating Versions

Packages using wildcard versions like 1.1.*, 4.20.*, 8.0.* are treated by Dependabot as version constraints, not specifications. When you specify 1.1.*, Dependabot interprets this as "I want any 1.1.x version" and considers you up-to-date as long as any 1.1.x exists—it will NOT suggest 1.2.* because that changes the constraint itself.

Secondary Issues:

• Low PR limit (5) may have queued some updates
• No dependency grouping caused PR fragmentation

Dependabot Configuration Fixes

Setting	Before	After	Impact
versioning-strategy	(default)	increase	Allows widening floating constraints
open-pull-requests-limit	5	10	More concurrent updates
groups	(none)	3 groups	Reduces PR noise

Test Plan

• CI build passes
• All unit tests pass
• Verify Dependabot creates grouped PRs on next scheduled run

Summary of Changes

Hello @joshsmithxrm, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on maintaining the project's health and security by updating several critical dependencies and significantly improving the automated dependency management system. The changes ensure that the project benefits from the latest features, security patches, and a more streamlined process for future dependency updates, addressing previous limitations in how Dependabot detected and proposed changes.

Highlights

• Dependency Updates: Updated Microsoft.PowerPlatform.Dataverse.Client to 1.2.*, which includes a fix for CVE-2022-26907, and System.CommandLine from a beta to its stable 2.0.1 release.
• Test Infrastructure Refresh: Upgraded core test packages including Microsoft.NET.Test.Sdk to 18.0.1, xunit to 2.9.3, and xunit.runner.visualstudio to 3.0.2 across all test projects.
• Dependabot Configuration Enhancement: Improved Dependabot's configuration by setting versioning-strategy: increase to correctly handle floating version updates, increasing the open-pull-requests-limit to 10, and introducing dependency grouping to reduce PR noise.

Code Review

This pull request successfully updates several outdated packages, including an important security fix for Microsoft.PowerPlatform.Dataverse.Client and a move to a stable release for System.CommandLine. The updates to the test infrastructure are also welcome. The core of this PR is the much-improved Dependabot configuration, which correctly adds versioning-strategy: increase to handle floating versions and introduces dependency grouping to reduce pull request noise. The changes are logical and well-documented. I have one minor suggestion regarding the CHANGELOG.md file to improve its structure and readability.
