Deprecate MinIO integration

[Copilot]

The MinIO OSS project was archived on February 14th, 2025 and is no longer maintained. Both CommunityToolkit.Aspire.Hosting.Minio and CommunityToolkit.Aspire.Minio.Client are deprecated to prevent community exposure to an unmaintained dependency.

Changes

• [Obsolete] on all public types in both packages — MinioContainerResource, MinioBuilderExtensions, MinioClientBuilderExtensionMethods, MinioClientSettings, HeaderAppInformation, MinioCredentials
• Package metadata — both .csproj descriptions and tag lists updated to surface deprecation via NuGet
• README warnings — both README.md files now open with a [!WARNING] callout linking to the archive notice
• Tests & examples — #pragma warning disable CS0618 added to all consuming files, consistent with existing patterns in the repo (Python Extensions, Java, MCP Inspector)

Usage now produces a build warning:

// CS0618: MinioBuilderExtensions is obsolete:
// 'The MinIO OSS project has been archived and is no longer maintained.
//  This integration is deprecated and will be removed in a future version.'
var minio = builder.AddMinioContainer("minio");

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

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

• dl.min.io
  • Triggering command: /usr/bin/minio minio server /data (dns block)

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)

Pull request overview

This PR deprecates the MinIO hosting and client integrations across the Aspire Community Toolkit to discourage usage of an unmaintained dependency, and updates docs/metadata/tests accordingly.

Changes:

• Mark MinIO public types as [Obsolete] to surface a CS0618 warning at compile time.
• Update NuGet package metadata (description/tags) and READMEs to clearly communicate deprecation.
• Suppress CS0618 warnings in tests and examples that intentionally continue to compile against the deprecated APIs.
