Microsoft.Azure.Functions.Worker.Extensions.OpenApi throws System.IO.FileNotFoundException

[lgp1985]

Describe the issue
I migrated a function app from .net 6.0 to 8.0 with the Upgrade wizard on Visual Studio 2022, on doing so, I changed the model from utilizing Microsoft.Azure.WebJobs.Extensions.OpenApi to Microsoft.Azure.Functions.Worker.Extensions.OpenApi.
My project relies on third party libraries that are outdated, but still usable for referencing models.

To Reproduce
Steps to reproduce the behavior:

1. Run function app
2. Open link for 'RenderSwaggerUI'
3. See error

Expected behavior
Should be able to see Swagger loading properly, as it's seen with Microsoft.Azure.WebJobs.Extensions.OpenApi, skipping any unused types custom attributes. Feels the code traverses all types regardless of those being used in any parts of swagger.

Hey guys, this is a small fix, and I even proposed a PR for that, can someone look into it?

Hi,

Is this project deprecated?
