[Bug]: Don't deploy on every push

### Problem description

Not necessarily a bug, but since I have the frontend and backend parts of my WebApp in one repo, every time I push something in the frontend, deno deploy starts a new build and deploys it, although nothing has changed.

Is there a possibility to prohibit deno from building? The main entrypoint is set to my server.ts in the backend folder, but still it builds every time (even on README changes)

### Steps to reproduce

Happens on every push

### Expected behavior

Only build and deploy, when file inside the backend folder are altered

### Environment

_No response_

### Possible solution

_No response_

### Additional context

Your help is much appreciated! :)
