[Aspire] calling infra synth does not generate the auto-gen inputs, leading to deployment fail

[vhvb1989]

For a manifest like

{
  "resources": {
    "cache": {
      "type": "container.v0",
      "connectionString": "{cache.bindings.tcp.host}:{cache.bindings.tcp.port}",
      "image": "redis:7.2.4",
      "bindings": {
        "tcp": {
          "scheme": "tcp",
          "protocol": "tcp",
          "transport": "tcp",
          "containerPort": 6379
        }
      }
    },
    "sql": {
      "type": "container.v0",
      "connectionString": "Server={sql.bindings.tcp.host},{sql.bindings.tcp.port};User ID=sa;Password={sql.inputs.password};TrustServerCertificate=true",
      "image": "mcr.microsoft.com/mssql/server:2022-latest",
      "env": {
        "ACCEPT_EULA": "Y",
        "MSSQL_SA_PASSWORD": "{sql.inputs.password}"
      },
      "bindings": {
        "tcp": {
          "scheme": "tcp",
          "protocol": "tcp",
          "transport": "tcp",
          "containerPort": 1433
        }
      },
      "inputs": {
        "password": {
          "type": "string",
          "secret": true,
          "default": {
            "generate": {
              "minLength": 10
            }
          }
        }
      }
    },
    "db": {
      "type": "value.v0",
      "connectionString": "{sql.connectionString};Database=db"
    }
  }
}

The input password is set as generate and it is correctly generated and used then azd runs up or provision.

However, if the first azd operation is azd infra synth , the input is not generated, leading to deployment issue
