Search for OpenAPI v3 filename

[Tasteful]

Regarding to OpenAPI.v3 the recommendation is that the spec name should be openapi.json or openapi.yaml. Should that be added to the searchpath's below?

HttpRepl/src/Microsoft.HttpRepl/ApiConnection.cs

Line 21 in 53e84a9

private const string SwaggerSearchPaths = "swagger.json|swagger/v1/swagger.json|/swagger.json|/swagger/v1/swagger.json";

Good call. You're right it probably should be.
