VertexAi depending ktor 2, time to update?

### [REQUIRED] Step 2: Describe your environment

* Android Studio version: Meerkat Feature Drop Canary 7
* Firebase Component: BOM, Crashlytics, Config, Messaging, Analytics and Vertexai
* Component version: 33.10.0

* Ktor version 3.1.1
* Coil 3.1.0

### [REQUIRED] Step 3: Describe the problem

Vertexai sdk is depending on a older version of ktor 2. And it makes apps running ktor 3 struggling.
I did read this on this closed issue [https://github.com/firebase/firebase-android-sdk/issues/6413](https://github.com/firebase/firebase-android-sdk/issues/6413) that ktor 3 was to new and you want to wait, it's been a while now so I'll raise this issue again.

#### Steps to reproduce:

You can run the app with ktor 3 enabled. But as soon as I call `generativeModel.startChat()` the client crash with `Caused by: java.lang.ClassNotFoundException: Didn't find class "io.ktor.client.plugins.HttpTimeout"`

Hope this can be fixed in a soon rather then later release.
Cheers.

Start by reviewing the linked closed issue 6413 and reproducing the crash with Ktor 3.1.1 when calling generativeModel.startChat(). Done means Vertex AI works in an app using Ktor 3 without the HttpTimeout ClassNotFoundException.
