chore: remove rosetta patch (#15001)

Our `yarn-upgrade` workflow is failing with:

```console
@lerna/[email protected] ✔

**ERROR** Failed to apply patch for package jsii-rosetta at path
  
    node_modules/jsii-rosetta

  This error was caused because jsii-rosetta has changed since you
  made the patch file for it. This introduced conflicts with your patch,
  just like a merge conflict in Git when separate incompatible changes are
  made to the same piece of code.
```

Basically, its not able to apply the [rosetta patch](https://github.com/aws/aws-cdk/blob/master/patches/jsii-rosetta%2B1.28.0.patch) anymore since a new version of `jsii-rosetta` has been released which creates conflicts. 

The new version of rosetta [addresses](aws/jsii#2816) the problem the patch was trying to solve, so it is no longer needed (yey).
