Use explicit imports

[frangio]

Note that because of Solidity override resolution (override(A, B)) sometimes it's necessary to import an identifier even if it's only used for that.

When both an interface and implementation are required, I've reused the same file for the import statement, as in:

import {IGovernor, Governor} from "../../governance/Governor.sol";

I think it may unexpectedly remove imported values that users might rely on. I'd say yes just for making sure it's mentioned somewhere.

LGTM, thank you for tackling this @frangio!

I just updated the docs references to also use explicit imports and added a linter rule to avoid global imports

Note: We have to move this example code to a separate file like the others in this article.
