[docs] Document AKS Standard control-plane tier default

[aspire-repo-bot]

Documents changes from microsoft/aspire#20917.

Target branch

Targeting release/17.0 based on the source PR milestone 17.0 (exact match on microsoft/aspire.dev).

Why this PR is needed

microsoft/aspire#20917 changes the default AKS control-plane tier for Aspire-managed clusters from Free to Standard, ahead of the integration moving toward general availability. This is a user-visible default-value change that affects billing (adds a cluster-management charge) and availability guarantees for every AppHost using AddAzureKubernetesEnvironment, with no corresponding mention in the existing aspire.dev docs for the AKS integration.

Triggered signals from the docs-check pre-step:

• integration_readme_changed — src/Aspire.Hosting.Azure.Kubernetes/README.md added a "Cluster tier" section in the source PR.
• pr_body_has_user_facing_section — the source PR body's "User-facing usage" section shows the new generated sku: { name: 'Base', tier: 'Standard' } and the ConfigureInfrastructure override to keep Free.
• pr_body_has_cli_flag_mention — matched on validation command text in the PR body (not an actual CLI flag, but confirms the recall-oriented doc-gap check was warranted here since the behavior change itself had no doc coverage).

What documentation was added

Added a new Cluster tier section (mirroring the source PR's README update) to:

• src/frontend/src/content/docs/integrations/cloud/azure/aks/index.mdx — the AKS hosting integration API reference.
• src/frontend/src/content/docs/deployment/kubernetes/aks.mdx — the end-to-end "Deploy to AKS" guide.

Both sections explain:

• The Standard tier is now the default, providing an uptime SLA for production workloads, and link to [AKS pricing tiers]((learn.microsoft.com/redacted) instead of embedding dollar amounts.
• The tier change does not affect node VM sizes, node counts, or application availability.
• Applying updated infrastructure to an existing Aspire-managed cluster changes its tier to Standard (and introduces the cluster-management charge) — upgrading the package alone does not modify a deployed cluster.
• How to opt back into the Free tier via ConfigureInfrastructure, using the exact C# snippet from the source PR.
