feat: detect non-member expressions in n/no-sync

[scagood]

This resolves named imports, or destructured requires:

import { readFileSync } from 'node:fs';

const file = readFileSync('/file/path');

const { readFileSync } = require('node:fs');

const file = readFileSync('/file/path');

This is the counterpoint to #128 and Option 1 for #102 (the simple option).
