[CONTENT REQUEST] Tutorial for minting NFTs on the XRP Ledger

[hammertoe]

I volunteer to write a tutorial for minting NFTs on the XRP Ledger. This will follow a very similar structure and process as the Polygon tutorial including using nft.storage. But will be a lot more concise as the XRP Ledger has native NFT functionality that does not require first creating or deploying a smart contract.
