URL validation during publish through provider

[alexcos20]

Do not use market's microservice to check the published URL, but use ocean.js instead

Market should use ocean.provider.fileinfo (https://github.com/oceanprotocol/ocean.js/blob/main/src/provider/Provider.ts#L81) instead of using it's own endpoint
(https://github.com/oceanprotocol/market/blob/main/src/utils/index.ts#L45)

Once this is done we should remove this endpoint https://fileinfo.oceanprotocol.com

think it's fine using ocean.js directly for checking URL since it's probably some exported method from there. So we might not need to do anything in react hooks for that. So guess we can move this through to market

[alexcos20]

yeah, I was not sure about react or market.
The function is here: https://github.com/oceanprotocol/ocean.js/blob/main/src/provider/Provider.ts#L76

[alexcos20]

ignore that, let me add a interface to that

done in oceanprotocol/ocean.js#542
