Replace Infura IPFS file upload in favor of Pinata

We have received reports of couple of users not having their affiliate data reflect/account for affiliate trades.
Upon investigation, the issue is that the file is not available on Pinata yet (see pic).
The file is on IPFS, but not yet propagated to Pinata.
When backend tries to fetch the doc to calculate the referrals it fails as the data is not yet available
We upload the file to an Infura endpoint and then later pin it with Pinata (

cowswap/src/custom/utils/metadata.ts

Line 53 in eefe076

await pinByHash(cid)

)
Reading their docs, I assumed there was no way to upload files using Pinata, but @alex proved me wrong.
Their pinining services not only mark a hash as pinned, but can also upload files/json etc.
In fact there's even a dedicated endpoint for JSON files https://docs.pinata.cloud/api-pinning/pin-json
So, the request is: Let's replace the ipfs-http-client lib for IPFS upload (

cowswap/src/custom/api/ipfs/index.ts

Line 8 in eefe076

const { create } = await import('ipfs-http-client')

) and use instead only Pinata.
With that hopefully the backend will have consistent data and no more users with missing data.
As soon as this is ready we should release it as a hotfix
