.Net: 404 when using WeaviateMemoryStore

[EcoleKeine]

Describe the bug
404 when using WeaviateMemoryStore

To Reproduce
Steps to reproduce the behavior:

	var memoryStore = new WeaviateMemoryStore("http://localhost:8080/v1");
	await foreach (var item in memoryStore.GetCollectionsAsync())
	{
		Console.WriteLine($"collectionName: {item}:");
	}

2. See error: HttpRequestException: Response status code does not indicate success: 404 (Not Found).

Reason
it call "http://localhost:8080/{path}" not "http://localhost:8080/v1/{path}"
see WeaviateMemoryStore.ExecuteHttpRequestAsync

new Uri(_endpoint, request.RequestUri);

new Uri(new Uri("http://localhost/v1"), "path") get "http://localhost/path", not "http://localhost/v1/path"
