[AspireDeployment] Environment service sends non-translated messages to caller

[anvillan]

Messages sent back to the caller of Environment.CreateEnvironment are not translated. E.g.:

This message is located here:

azure-dev/cli/azd/internal/vsrpc/environment_service_create.go

Line 63 in f67bbd7

_ = observer.OnNext(ctx, newImportantProgressMessage("Analyzing Aspire Application (this might take a moment...)"))

Ideally, this message -and all messages returned by the services exposed by the AzDev server- should be translated.

This would require not only defining the all the translated messages packages, but also a way to communicate the current locale of the client (caller). This configuration might be passed through Server.Initialize() endpoint.

Note: a bug for this has been already open for VS IDE. Bug 2291999, Area path DevDiv\Web Tools\Aspire
