Cant publish to Function App with app settings as Key Vault references

[mlassbo]

Does this occur consistently? Yes
Repro steps:

1. Create a function app (Linux consumption plan in my case) with the AzureWebJobsStorage setting as a Key Vault reference
2. Publish a function to the function app using the command line, e.g. func azure functionapp publish myfuncapp

Action: azureFunctions.deploy
Error type: SyntaxError
Error Message: Connection string contains unrecognized key: "@Microsoft.KeyVault(SecretUri"

Could be related to #1934 and Azure/azure-functions-host#5306

The platform team already has a fix for 5306, but not sure when it's rolling out. Might be worth waiting to see if that fixes it since it also applies to KeyVault app settings
