CS4014 warning when returning ValueTask instead of Task

[BramMusters]

Description

Hangfire throws CS4014 compilation warning when enqueuing async jobs that return ValueTask instead of Task.

Steps to Reproduce

Working case with Task:

public async Task ProcessDataAsync_Task(int id)
{
    // Async operation
    await Task.Delay(100);
    // Process data
}

// Works fine, builds successfully
BackgroundJob.Enqueue(() => ProcessDataAsync_Task(123));

Failing case with ValueTask:

public async ValueTask ProcessDataAsync_ValueTask(int id)
{
    // Async operation
    await Task.Delay(100);
    // Process data
}

// Compiler warning CS4014
BackgroundJob.Enqueue(() => ProcessDataAsync_ValueTask(123));

Expected Behavior

Hangfire should support enqueuing methods that return ValueTask just as it supports methods that return Task, without throwing CS4014 compilation errors.
