[OP] As a Passport holder, I want to mint an test net Github account attestation via the Attestation Station

As a Passport holder, I want to mint an test net Github account attestation via the Attestation Station

GIVEN I am a Passport holder with a verified Github account stamp in my Gitcoin Passport on Ceramic AND I am connected to the Optimism Goerli test net WHEN I click the "Mint" button THEN am prompted to pay the necessary gas fees for minting the attestation

GIVEN I succesfully sign a Goerli transaction to pay the gas fees WHEN the transction is confirmed THEN the attestation is minted via the Attestation Station

Notes:

• Don't worry about a design and the data structure of the key and val fields
• Attestation station docs: https://community.optimism.io/docs/governance/attestation-station/#general-faq
• Optimism Goerli Attestation Station contract address: https://community.optimism.io/docs/governance/attestation-station/#general-faq
• Invesitage wehther we can pass a signed (from our IAM) transaction to the Passport holder so they can sign it and pay the gas. If that is not possible, the IAM will have to pay the gas
• Example UI and corresponding repo:

Regarding the data structure of the attestation station: https://community.optimism.io/docs/governance/attestation-station/#state

To my understanding the mapping could be as follows:

A. creator (gitcoin smart contract) => about (passport owner) => stamp key (Twitter|TwitterFollowerGT100|TwitterFollowerGT500| ... => val (bytes)

or it could be like:

B. creator (gitcoin smart contract) => about (passport owner) => stamp key (hash) => val (Twitter|TwitterFollowerGT100|TwitterFollowerGT500| ....)

Option A would allow an easy check to see if a user owns a given stamp or not. But it make deduplication hard. On the other hand maybe we do not need deduplication at this level, and this would be done in the Scorer ....

For reference, what would be needed to fulfil the requirements are raw transactions, that are build in the BE and sent to the FE for the user to sign: https://ethereum.stackexchange.com/questions/63805/issues-while-sending-raw-transaction-for-calling-smart-contract-methods

However to be clarified / tested: in the context of the AttestationStation, who is considered the issuer? Is it the user? We need the issuer to be Gitcoin (basically a Gitcoin owned address). But I am not sure this is the case.
