object_store: Azure brokenness on 0.12.0

[a10y]

Describe the bug

I've been investigating some Vortex queries on Azure Blob Store Gen2. I've created a simple storage account, populated some files, and was just trying to list the bucket on 0.12

Cargo.toml:

[package]
name = "rustazuretest"
version = "0.1.0"
edition = "2024"

[dependencies]
tokio = { version = "1", features = ["full"] }
object_store = { version = "=0.12", features = ["azure"] }
futures = "0.3"

main.rs

use futures::StreamExt;
use object_store::azure::MicrosoftAzureBuilder;
use object_store::ObjectStore;

#[tokio::main]
async fn main() {
    let account = "vortexicebergsummit25";
    let access_key = "REDACTED";
    let container_name = "tpch";

    let azure = MicrosoftAzureBuilder::new()
        .with_account(account)
        .with_access_key(access_key)
        .with_container_name(container_name)
        .build()
        .expect("azure object store");

    let mut objects = azure.list(None);
    while let Some(next) = objects.next().await {
        println!("Object: {:?}", next.unwrap());
    }
}

On 0.12 this results in an error:

called `Result::unwrap()` on an `Err` value: Generic { store: "MicrosoftAzure", source: ListRequest { source: RetryError { method: GET, uri: Some(https://vortexicebergsummit25.blob.core.windows.net/tpch?&restype=container&comp=list), retries: 0, max_retries: 10, elapsed: 61.271375ms, retry_timeout: 180s, inner: Status { status: 403, body: Some("\u{feff}<?xml version=\"1.0\" encoding=\"utf-8\"?><Error><Code>AuthenticationFailed</Code><Message>Server failed to authenticate the request.

stack backtrace:

However, if I forcibly pin to 0.11.2, it works

[package]
name = "rustazuretest"
version = "0.1.0"
edition = "2024"

[dependencies]
tokio = { version = "1", features = ["full"] }
object_store = { version = "=0.11.2", features = ["azure"] }
futures = "0.3"
