Describe the bug

I have a Rest API with the following route: GET /api/contracts/, which returns a list of contracts. There's also one query param type, which is used to filter the contract list.

Kiota will create a ContractsRequestBuilder with the following constructor:
public ContractsRequestBuilder(Dictionary<string, object> pathParameters, IRequestAdapter requestAdapter) : base(requestAdapter, "{+baseurl}/api/contracts/{?type*}", pathParameters)
As you can see, type is part of the URL.

Now when you add the route GET /api/contracts/lease/, Kiota will omit all query params for /api/contracts and create the following constructor:
public ContractsRequestBuilder(Dictionary<string, object> pathParameters, IRequestAdapter requestAdapter) : base(requestAdapter, "{+baseurl}/api/contracts", pathParameters)
As you can see, type is NOT part of the URL anymore. Even if you can set the query param in code, it won't be added to the request.

Expected behavior

Query params not being omitted in the request.

How to reproduce

Use the OpenAPI description file to generate a client with kiota.
I'm using the following command:
kiota generate -l csharp -d Api.json -c ApiClient -n MyProject.Client -o ./Client --clean-output --backing-store

If you remove the route "/api/contracts/lease/", it will work as expected.
