feat(linter): Add "strict" option to promise/prefer-await-to-then rule (#8674)

Implementation of the strict option [specified in the eslint docs for
`promise/prefer-await-to-then`](https://github.com/eslint-community/eslint-plugin-promise/blob/main/docs/rules/prefer-await-to-then.md)

```js
// Examples of **incorrect** code with `{ strict: true }`:
async function hi() {
  await thing().then(x => {})
}
```
