Can't update change index.html when running Firebase Hosting locally
As you are using Firebase Hosting with Cloud Run, unfortunately, it's necessary to use these commands, as you need to containerize the app and upload it to Container Registry, so it can be deployed. For example, even in this simple Hello World
example, it needs to have the commands run.
To summarize, considering the structure and format of your application - deploying with Cloud Run - it will be needed for you to execute the commands, so the application is containerized and uploaded properly, so the deploy occurs correctly. You can get all the details via official documentation here as well.
