Add yarn ipfs command to deploy on IPFS

[portdeveloper]

This PR:

-> Adds yarn ipfs command to the package.json
-> Modifies next.config.js to populate out folder when yarn ipfs is run
-> Adds a deploy-ipfs.js file under packages/nextjs/scripts

The user has to have an ipfs daemon running for the initial uploading.

Here is an example I deployed using this script + eth.limo
https://pallas-athena.eth.limo/
it should be garbage collected after some time but it has been up almost for a week now.

Is it possible to avoid daemon? For example using https://web3.storage/docs/w3up-client/ or https://docs.storacha.network/w3up-client/ ? Asking without trying, but probably it simplifies DX

[portdeveloper]

Yeah, that is a valid concern, but I wanted to keep everything manual just for the sake of showing that it can be done this way.

Thanks @portdeveloper !!

Could you update this using the nifty ink server? I know it doesn't work (because of how that server is configured), but we are working on a proper BG IPFS network of nodes, so when the time is right (probably in a week or so) it'd be a matter of replacing the nifty ink URL.

cc @rin-st (because of #1030 (comment))

Nice job @portdeveloper !!

Just tried the previous version before 1547922 on Windows environment, and ran into a couple of issues, I had to do this in order to run yarn ipfs:

• Renamed deploy-ipfs.js to .mjs because i was getting a Cannot use import statement outside a module error. Then updated package.json accordingly
• Created the out folder manually as it wasn't being generated automatically during the build process.

After that it deployed to ipfs nicely with my IPFS Desktop app running 🙏

Thanks for testing @Pabl0cks !

Changing the script name to mjs really makes sense here, I have added the commit.

But I wonder why the out folder is not created automatically.

yarn ipfs command has yarn build in it so it should be triggering a build. I will be testing this in another computer to make sure.

@portdeveloper working great!!

I have the same issue with the out folder:

Uploading to Nifty Ink IPFS...
📦 Adding directory to IPFS via Nifty Ink...
Error adding directory to IPFS: [Error: ENOENT: no such file or directory, stat '/ssd/workspace/buidlguidl/scaffold-eth-2/packages/nextjs/out'] {
errno: -2,
code: 'ENOENT',
syscall: 'stat',
path: '/ssd/workspace/buidlguidl/scaffold-eth-2/packages/nextjs/out'
}

I had to create it manually. When and where should it be created?

@damianmarti Thanks for the feedback I am looking into it right now!
