change UI so users can issue attestation as multiple attester orgs

[divine-comedian]

in #167 users will be able to issue multiple attestations in one transaction using a new contract. This will allow users to issue a vouch or flag as one or more attester orgs that they belong to, each one becoming a separate attestation.

the UX of vouching or flaggin will need a simple change of the attester orgs selection component to be multi select instead of single select. some slight copy changes will be required on the same modal.

even if the user issues an attestation at once as multiple attester orgs they will still be treated separately on the table of attestation data for users and project. We will not need any UI changes in how we handle editing and deleting a particular attestation

@Tosinolawale - can you mock this one up, very small change I think UX wise

• users can select multiple groups to attest as if they are eligible members.
• one comment is issued even if they are attesting as multiple groups
• need to handle minting gitcoin passport feature

@mateodaza for you to take a look at once smart contract is deployed on testnet and BE is integrated and working.

In addition we'll need to handle this mateo so we are issuing multiple attestations - you can find an example in their SDK docs here: https://docs.attest.org/docs/developer-tools/eas-sdk#example-creating-multi-onchain-attestations
