Pull request overview

Updates Azure SQL Managed Instance update policy documentation to reflect that Query Store on secondary replicas is available only when using the Always-up-to-date policy.

Changes:

• Add “Query Store for secondary replicas” to the Always-up-to-date policy feature list.
• Keep the existing note that Always-up-to-date includes SQL Server 2025 policy features with specific exceptions.

[Copilot]

In the Always-up-to-date table cell, the last line break is written as <br />- All features... (missing a space after <br />), which can render poorly in the table. Also, the new link text uses title case ("Secondary Replicas") while the rest of the table and other docs use sentence case ("secondary replicas"); please align the link text/capitalization for consistency.
