Please port to main as well

@wtgodbe main is on latest 3.x already (#66998)

[Youssef1313]

Well, there was a newer version released for 3.x only 3 weeks ago. Let me update to 3.7.0: #67468

Looks like there's a test failure in OpenApiDocumentIntegrationTests.VerifyOpenApiDocument(documentName: "schemas-by-ref", version: OpenApi3_0)

[Youssef1313]

@copilot Update the test so that it passes.

[Youssef1313]

It looks like Microsoft.OpenApi might have changed some behavior - hopefully it's fine as long as it's correct and compliant with the spec.

[Copilot]

@copilot Update the test so that it passes.

Updated the schemas-by-ref OpenAPI 3.0 snapshot in commit b158b60. The change reflects how OpenApi 2.7.5 serializes nullable schemas differently — nullable: true and the type are now emitted at the parent allOf level rather than as a separate sibling schema inside the allOf array. All 14 VerifyOpenApiDocument tests now pass.

Fixed in the latest commit. The OpenQA.Selenium.BiDi.Communication namespace was removed in Selenium 4.44.0 (which this repo uses). The using directive in both files was unused — no types from that namespace were actually referenced in either file — so removing it is sufficient.
