braket spacing and indenting in import directives

[Janther]

Simple enough.

before the PR while using bracketSpacing = true we would print:

import {symbol1 as alias, symbol2} from "File.sol";
import {symbol1 as alias1, symbol2 as alias2, symbol3 as alias3, symbol4} from "File2.sol";

after the PR:

import { symbol1 as alias, symbol2 } from "File.sol";
import {
    symbol1 as alias1,
    symbol2 as alias2,
    symbol3 as alias3,
    symbol4
} from "File2.sol";

It is a case that I didn't even know existed in import rules 😂
