All items created by `RollbarMiddleware` have the same title

[srmagura]

Describe the bug Whenever an exception is caught by RollbarMiddleware, it creates an item with the title "RollbarMiddleware processed uncaught exception."

This causes the dashboard to have many items with the same title, even when there are many different exceptions that have occurred in different parts of the codebase.

To Reproduce Throw an exception in an ASP.NET Core app, with the RollbarMiddleware configured.

Expected behavior I would like to see the original exception message in the title of the Rollbar item.

Rollbar Client - Rollbar.NET Hosting Environment (please complete the following information):

• Rollbar.NET Host type: ASP.NET Core
• OS and its version: Windows 11
• .NET flavor and its version: .NET 8
• Application framework and its version: ASP.NET Core
• Rollbar.NET Version: 5.2.0
• Applicable Rollbar Plug-in (if any):
• Applicable custom third party logging library/framework integration (if any):
• Applicable Browser (if any):

Additional context I know I can copy the RollbarMiddleware source code into my code to fix this, but ideally that would not be necessary.

I worked around this limitation by creating my own Rollbar middleware, based on the official one: https://github.com/rollbar/Rollbar.NET/blob/master/Rollbar.NetCore.AspNet/RollbarMiddleware.cs

Delete the "title" argument from this line.
