Setting the bucket CORS header

Some browser operations require the domain to be whitelisted by the CORS header. We setup firebase to whitelist our domain by providing a cors.json config file to gsutil.

[
    {
        "origin": ["https://mytale.io", "http://localhost:5173"],
        "method": ["GET"],
        "maxAgeSeconds": 3600
    }
]

gsutil cors set cors.json gs://mytale.firebasestorage.app
