[katopz]

Issue description

Follow an instructions then try sugar validate and get an error

"assets/0.json: missing field `category`

Refer to metaplex doc there's no category

https://docs.metaplex.com/candy-machine-v2/preparing-assets#-metadata-0json

{
"name": "Number #0001",
"symbol": "NB",
"description": "Collection of 10 numbers on the blockchain. This is the number 1/10.",
"seller_fee_basis_points": 500,
"image": "0.png",
"attributes": [
{ "trait_type": "Layer-1", "value": "0" },
{ "trait_type": "Layer-2", "value": "0" },
{ "trait_type": "Layer-3", "value": "0" },
{ "trait_type": "Layer-4", "value": "1" }
],
"properties": {
"creators": [
{ "address": "N4f6zftYsuu4yT7icsjLwh4i6pB1zvvKbseHj2NmSQw", "share": 100 }
],
"files": [{ "uri": "0.png", "type": "image/png" }]
},
"collection": { "name": "numbers", "family": "numbers" }
}

But in sugar test case there is category

https://github.com/katopz/sugar/blob/04b334f2bb23605d95749e69d9c6fcd6fe7d9157/script/sugar-cli-test.sh

{
"name": "[$TIMESTAMP] Collection",
"symbol": "TEST",
"description": "Sugar CLI Collection",
"seller_fee_basis_points": 500,
"image": "collection.png",
"attributes": [{"trait_type": "Flavour", "value": "Sugar"}],
"properties": {
"files": [
{
"uri": "collection.png",
"type": "image/png"
}],
"category": "Sugar Test Collection"
}
}

Seem to be doc issue?

Priority this issue should have

Medium (should be fixed soon)

Our parsing currently refers to an older version of the JSON spec. For now, feel free to just run sugar upload and sugar deploy manually and skip the validate step.
