Issue:
Unresolved resource dependencies [ServerlessDeploymentBucket]
# Bug Report

## Description
I started receiving a `Template format error: Unresolved resource dependencies [ServerlessDeploymentBucket] in the Resources block of the templat` error on my CD pipeline, probably after the https://github.com/serverless/serverless/commit/7b351c7ada543cd3af8713f62942009beb6ed7ef release. (I know that because I was using `npx serverless deploy` and it stopped working around 30 minutes ago. 🤔)
<!-- Please use https://forum.serverless.com, StackOverflow or other forums for Q&A -->
<!-- Please answer ALL the question below. Otherwise we probably have to close the issue due to missing information -->

**1. What did you do?**
Simply `npx serverless deploy` on my CD pipeline as we always do
**2. What happened?**
Started to fail because of a `Unresolved resource dependency` on the `ServerlessDeploymentBucket` even after successfully uploading the package to AWS S3 
**3. What should've happened?**
A successful deployment
**4. What's the content of your `serverless.yml` file?**

Issue discussion:
I just encountered the same problem. It was working fine yesterday running version 1.55.1
@flpStrri great thanks for report! Indeed it's a regression introduced with #6823. Fix is on the way
Just adding an extra info, just ran `npx serverless@1.55.1 deploy --stage zdca106` and it worked. 💃 
The issue seems to be with the newly added deployment bucket policy that references an export that doesn't exist.
