Misleading description in AuthConfig.js of GlobalValidation.ExcludedPaths property.

The [current description](https://github.com/Azure/azure-rest-api-specs/blob/48cba8646b6cb51ce77bd95a2a8c3dddca068459/specification/app/resource-manager/Microsoft.App/stable/2022-03-01/AuthConfigs.json#L331C10-L331C112) says:

> The paths for which unauthenticated flow would not be redirected to the login page.

However, that is only true if the `UnauthenticatedClientAction` property is set to `UnauthenticatedClientActionV2.RedirectToLoginPage`.

My experience is that a description like this would be more accurate:
> The paths for which unauthenticated flow would not take the UnauthenticatedClientAction

Raising this after being pointed here from https://github.com/Azure/azure-sdk-for-net/issues/51569

Start with specification/app/resource-manager/Microsoft.App/stable/2022-03-01/AuthConfigs.json around line 331 and inspect the GlobalValidation.ExcludedPaths description alongside UnauthenticatedClientAction. Update the description so it accurately covers the configured unauthenticated action, then verify the generated AuthConfig.js description reflects the correction.
