PR Summary

This pull request adds support for the automatic registration and protection of the Microsoft Artifact Registry (MAR) repository in the PSResourceGet module. MAR is now registered by default alongside PSGallery, with a higher priority and trusted status. The changes ensure MAR cannot be manually registered, have its URI or credentials set, and update the documentation and tests to reflect its new behavior.

MAR Repository Registration and Protection

MAR is now automatically registered with default values (name, URI, priority, trusted status, and API version) when the repository store is created or reset, and appears in the default repository XML file. [1] [2] [3] [4]
Added logic to prevent manual registration of MAR via the Register-PSResourceRepository cmdlet, including case-insensitive name checking and error handling for hashtable registration. [1] [2] [3]
Prevented changes to MAR's URI or credentials via the Set-PSResourceRepository cmdlet, with appropriate error messages.
Updated dynamic parameter logic to ensure credential provider options are not shown for MAR.

Documentation and Messaging Updates

Updated commandlet documentation and verbose messages to indicate that both PSGallery and MAR are registered by default and after a reset. [1] [2] [3]

Testing Enhancements

Added new test utilities and a comprehensive test suite for MAR, verifying its default registration, protection against manual registration and modification, and behavior during repository store reset operations. [1] [2] [3]
