[CONTENT] Smart contract example - Flow

[dchoi27]

We should have a page /smart-contract-examples/flow giving a lightweight tutorial for minting a Flow smart contract on NFT.Storage.

Let's make a simple example that:

• [ ] Gives an intro to Flow
• [ ] Gives an example of minting an Flow smart contract for a PFP on Flow and NFT.Storage

Alternatively, we can leverage @jochasinga 's Flowwow tutorial here, though the goal of this page would be to have a really simple single smart contract example, and we can potentially use Flowwow better in the /tutorials section.

Note for the community: If you are interested in helping out, please do comment below!

Note for whoever tackles: Flow does have a metadata spec but metadata is kept on-chain

I can tackle this shortly after the AVAX tuturial.
