Duplicate parameters on operation filter

[erwinkramer]

Describe the bug
Getting duplicate parameter definitions when filtering on 2 or more operations that have the same parameters. That's an invalid OpenAPI definition.

OpenApi File To Reproduce

hidi transform -d https://raw.githubusercontent.com/microsoftgraph/msgraph-metadata/refs/heads/master/openapi/v1.0/openapi.yaml -f yaml -o ".\test.yaml" -v OpenApi3_0 --op certificateBasedAuthConfiguration.certificateBasedAuthConfiguration.UpdateCertificateBasedAuthConfiguration,certificateBasedAuthConfiguration.certificateBasedAuthConfiguration.DeleteCertificateBasedAuthConfiguration --co

Check the certificateBasedAuthConfiguration-id parameter in this case.

Expected behavior
Should just have a single parameter if it's exactly the same.

Additional context
Also tested directly with method OpenApiFilterService.CreateFilteredDocument with the same behavior.
