Ordering tags alphanumerically

Building a c# Azure functions API, using .Net8, isolated. v1.5.1 of the OpenApi package

I have about 13 endpoints and 6 tags, where some endpoints are under more then 1 tag. The endpoints are in 4 separate classes, for various resons.

The order the tags are displayed on the swagger ui seems to be somewhat related to the order they are encountered in the code but in no way is it alphanumerically ordered. I even tried to add numbers at the start of the tags but this did not change the order the tags were displayed.

There should be a way to control this, and the default should be alphanumerically I think.

Similar to [issue 339](https://github.com/Azure/azure-functions-openapi-extension/issues/339)

Reproduce the ordering with a C# Azure Functions isolated .NET 8 app using the OpenAPI package, with endpoints spread across classes and multiple tags. Trace how tags reach Swagger UI; done should mean a deterministic alphanumeric default or a documented way to configure the order.
