Problem purchasing a subscription in contracts 3.3.x on mumbai

[aaitor]

Describe the bug

When testing the upgrade of contracts v3.3.x in mumbai we are getting an error from the SDK when claiming a NFT: Nevermined does not have operator role

This seems because the TransferNFT721Condition is not an operator. Granting a condition as operator typically happens during the contract deployment.

Tasks:

• Check if during the upgredability process this needs to be granted again because the new condition implementation.
• Grant the TransferNFT721Condition v3.3.x in mumbai
• Modify the upgradability scripts please to include that

To Reproduce

Steps to reproduce the behavior:

1. Go to https://mumbai.nevermined.app/
2. Try to purchase a subscription

Expected behavior

The subscription is purchased and transfer correctly
