Pull request overview
Updates the Azure.Monitor.OpenTelemetry.AspNetCore package README to more clearly communicate that calling AddOpenTelemetry().UseAzureMonitor() multiple times is not supported, addressing confusion reported in #54616.
Changes:
- Clarifies the README note about multiple calls to
AddOpenTelemetry.UseAzureMonitor(). - Emphasizes that multiple calls are not allowed (instead of implying they harmlessly coalesce).

Addresses #54616 . Calling UseAzureMonitor twice isn't allowed, so I've updated the docs to make it clearer because saying it does not result in two exporters might mislead users into thinking that it can still be called.
