Circular references in external documents create an infinite recursion

Describe the bug
Open api documents that contain circular references create an infinite recursion because each external document is loaded into a new root workspace rather than the initial document loader workspace.

OpenApi File To Reproduce
In order to reproduce, you need two files that reference each other. I've put a circular reference in the schemas section of the below specs (this is not the exact problem I'm seeing with real documents, but it's close enough to reproduce). The references are hard coded to a mount directory because I'm using kiota as a driver, so you may need to update the paths if you run against a different location.

pet.json
pets2.json

Expected behavior
I believe external documents should all be loaded into the same workspace for reference resolution.

Screenshots/Code Snippets

docker run --rm `
    -v "${PWD}\output:/app/output" `
    -v "${PWD}\specs:/app/specs" `
    -u root `
    mcr.microsoft.com/openapi/kiota generate --language csharp -n MyCode --openapi ./specs/pet.json --log-level trace

I have encountered the problem in open api documents from large enterprise software providers, so I've attached a patch file that contains my work around for an internal fork of the document loader libraries. Adding external documents to the root workspace created by the initial document load appears to resolve the problem, though I'm not sure if the external references are being resolved correctly.

This patch includes the changes I was required to make in order to resolve locally.
circular_ref.patch

Reproduisez la récursion avec les fichiers liés pet.json et pets2.json à l’aide de la commande Docker Kiota fournie, puis suivez la manière dont les documents externes sont chargés dans les espaces de travail lors de la résolution des références. Comparez le circular_ref.patch joint avec le comportement actuel ; le travail est considéré comme terminé lorsque des documents externes se référant mutuellement sont résolus sans récursion infinie tout en restant dans l’espace de travail prévu.
