Different icons and splash images are being used

### :information_source: Info
Flutter Launcher Icons version:

- Previously: 0.13.1
- Updated to: 0.14.4

Flutter version:

- Previously: 3.24.5
- Updated to: 3.32.8

### :speech_balloon: Description
In our app, we use different icons and splash images for the staging and production environments.
The icon files are named as follows:

android-dynamic-icon-nobg_stg.png
android-icon-nobg.png

We also maintain separate YAML configuration files for flutter_launcher_icons:

flutter_launcher_icons-stg.yaml
flutter_launcher_icons-prd.yaml

App builds are separated in the Makefile using:

build-stg:
build-prd:

After upgrading flutter_launcher_icons to version 0.14.4, we encountered an issue where building the production app using `build-prd:` and uploading it to the Google Play Console results in the production app showing the icon from `build-stg:`.
However, the App ID, Base URL, and API settings are correctly using the `build-prd:` configuration.
This issue does not occur 100% of the time. Rebuilding the production app after the issue occurs usually resolves it.
Also, there were no changes to the icon images or the flutter_launcher_icons YAML files in this release.
Due to this instability, we would appreciate any investigation, fixes, or recommended workarounds to prevent this from happening again.
