feat(linter): add fixer for no-single-promise-in-promise-methods (#3531)

Fixes look like this:

```rs
let fix = vec![
    ("Promise.all([null]).then()", "Promise.resolve(null).then()", None),
    ("let x = await Promise.all([foo()])", "let x = await foo()", None),
    ("let x = await (Promise.all([foo()]))", "let x = await (foo())", None),
];
```
