Some Vision Studio links reference old docs or "404" pages. If Azure-Samples/azure-vision-sdk is the wrong samples place, then remove.

- [ ] feature request
- [X] documentation issue or request
- [ ] regression (a behavior that used to work and stopped in a new release)

Minimal steps to reproduce

I'm logging this because the documentation and samples for for Vision SDK a Vision REST API is very confusing and just trying to help eliminate some confusion.

1. If this repo "Azure-Samples/azure-vision-sdk" is the wrong location for samples then please remove or provide a big warning or a redirect to the correct samples.

This Github issue seems to indicate this is the wrong place for samples: #76 (comment)

2. For all features, in the "Try it out" view the "Use REST API" link goes to a 404 not found page (returned in JSON)

(NOTE: In Vision Studio, the links depend on which vision "feature" is selected on the start page. This is also slightly confusing, but I get it.)

the link currently goes to:
https://centraluseuap.dev.cognitive.microsoft.com/docs/services/unified-vision-apis-public-preview-2023-02-01-preview/operations/61d65934cd35050c20f73ab6

if change "centraluseuap" to "eastus" in the domain then the link will work (not sure if that actually is the intended location):

https://eastus.dev.cognitive.microsoft.com/docs/services/unified-vision-apis-public-preview-2023-02-01-preview/operations/61d65934cd35050c20f73ab6

3. The "Extract common tags from images" feature, in the "Try it out" view, the "View Samples on Github" link goes to obsolete documentation according to this Github issue: #76 (comment)

According to that issue the link should probably go to: https://github.com/Azure/azure-sdk-for-net/tree/main/sdk/vision/Azure.AI.Vision.ImageAnalysis/samples

Expected/desired behavior

Links should work and point to current samples.
