When syncing icons, if an Icon has been removed, the Android resource is not deleted.

**Describe the bug**

When syncing icons, if an Icon has been removed, the Android resource is not deleted.

**To Reproduce**
Steps to reproduce the behavior:
1. Delete an Icon from Figma
2. Sync the icons
3. Observe that the Android drawable resource is not deleted

**Expected behavior**

The Android drawable resource is not deleted

**Additional context**

See for instance in this PR: https://github.com/element-hq/compound-design-tokens/pull/249. The file `assets/android/res/drawable/ic_compound_folder.xml` should have been deleted.

A solution could be to delete all the Android resource before syncing. This is what we [do](https://github.com/element-hq/element-x-android/blob/main/tools/compound/import_tokens.sh#L33) when we import the token to Element X Android. But since the drawables are not removed from the source (this project), they are imported again, and lead to unused resources in the project EXA.
