Revert latest OpenAPI updates

This is causing a live site issue because DevX API reads OpenAPI document directly from GitHub for snippet generation. Reverting to last known good state, i.e. last week's update. We will hit this issue again tomorrow when the generation schedule kicks in.

kiota command mentioned in the original issue works with the OpenAPI document from this branch:

C:\github\kiota\src\kiota\bin\Debug\net6.0\kiota.exe -d https://raw.githubusercontent.com/microsoftgraph/msgraph-metadata/zengin/revert/openapi/v1.0/openapi.yaml --language typescript -o C:\test_typescript -c GraphBaseServiceClient -n MicrosoftGraph
