In 11-revoke-roles.js, it incorrectly revokes minting role for Governance/Vote contract

[Hampton-Black]

I believe the recommended code in tutorial for 11-revoke-roles.js incorrectly revokes all minting roles, including the vote/governance contract.

Specifically, in this line:
await token.roles.setAll({ admin: [], minter: [] });

On my local end, I noticed both my personal wallet and the vote contract held minting roles in the 'before' section, and then all were revoked in the 'after' section.

Recommended fix would be to just specify the role to revoke. i.e.:

await token.roles.revoke("admin", process.env.WALLET_ADDRESS);
await token.roles.revoke("minter", process.env.WALLET_ADDRESS);
