Build target emits warning for Blob/Queue trigger when connection is in user secrets file

[phenning]

Opening this here since it impacts template creation scenario. The problem is likely in the the Blob/Queue triggers themselves though since problem does not occur with CosmosDB trigger.

Repro Steps:

1. Create a NET 6.0 (LTS) project in Visual Studio, I re-proed this with non-isolated.
2. Select Blob Trigger (also repros with Queue trigger) and Configure Dependencies:
   
3. Select Storage Azurite emulator
4. Next, select "Store in local secrets file"
5. Finish connected services.

Build: observe following error:

1>+++++\.nuget\packages\microsoft.net.sdk.functions\4.2.0\build\Microsoft.NET.Sdk.Functions.Build.targets(32,5): warning : Function [Function1]: cannot find value named 'BlobConnectionString' in local.settings.json that matches 'connection' property set on 'blobTrigger'
1>+++++\.nuget\packages\microsoft.net.sdk.functions\4.2.0\build\Microsoft.NET.Sdk.Functions.Build.targets(32,5): warning :
1>Done building project "FunctionApp32.csproj".

Project runs without a problem, and user secrets file contains:
{
"BlobConnectionString": "UseDevelopmentStorage=true",
"BlobConnectionString:queue": "UseDevelopmentStorage=true",
"BlobConnectionString:blob": "UseDevelopmentStorage=true"
}

local.Settings.json contains:
{
"IsEncrypted": false,
"Values": {
"AzureWebJobsStorage": "UseDevelopmentStorage=true",
"FUNCTIONS_WORKER_RUNTIME": "dotnet"
}
}

If I copy the BlobConnectionString into the local.Settings.json file, the warning goes away.
