Invalid environment name defaults to production instead of failing gracefully

I am trying to setup deployment of my web app to a preview environment where `DEPLOYMENT_ENVIRONMENT` is generated dynamically.

I am following the documentation in https://learn.microsoft.com/en-us/azure/static-web-apps/gitlab?tabs=vanilla-javascript
which instructs to use the following image: `registry.gitlab.com/static-web-apps/azure-static-web-apps-deploy`.
The image reads `DEPLOYMENT_ENVIRONMENT` variable to determine target environment.

If the environment name does not meet strict naming requirements (max 16 characters, limited ascii charset), the deployment defaults to Production.

**To Reproduce**
Steps to reproduce the behavior:
1. run `registry.gitlab.com/static-web-apps/azure-static-web-apps-deploy` image with invalid environment name (`DEPLOYMENT_ENVIRONMENT`) longer than 16 characters
2. An error message is printed out
> The environment name provided exceeds the character limit of 16.
3. Happy success message follows:
> Deployment Complete :)
> Visit your site at: https://your-production-app.azurestaticapps.net/

This results in the app being deployed to production instead of preview environment.

**Expected behavior**
Deployment should fail since environment name is not valid.
