[espresso] Replace deprecated getObservatoryUri (#5788)

Replaces the deprecated `getObservatoryUri` with the newer `getVMServiceUri` now that this package requires 3.10, where it was introduced.

The methods have exactly the same implementation, so this is a no-op behaviorally.

Fixes flutter/flutter#131708
