GitHub file size badge doesn't work for some files #10548

Are you experiencing an issue with...

shields.io

🐞 Description

This badge works for most files
https://img.shields.io/github/size/badges/shields/server.js
but there are some that cause a problem
https://img.shields.io/github/size/badges/shields/package.json
The reason this fails is because this causes us to look for a file called "package" and use json output format, rather than look for a file called "package.json"

💡 Possible Solution

We might need to switch path from a path param to a query param to solve this.
