AWS grafana documentation change
Summary
Updated API key documentation to reflect deprecation and removal in version 12, changed note to Important, and updated links to point to versioned documentation.
Security assessment
The change explicitly deprecates API keys and recommends using service accounts instead, which is a security best practice for authentication. However, there is no evidence of a specific security vulnerability being addressed; this appears to be a planned deprecation and feature evolution. The change adds documentation about the security feature of service accounts.
