#### Add support for "Explicit Resource Management" proposal (#13752 by @fisker)

The Stage 2 proposal ["Explicit Resource Management"](https://github.com/tc39/proposal-explicit-resource-management/) is now supported via Babel 7.20.0. Also keep in mind our [policy on non-standardized syntax](https://prettier.io/docs/en/rationale.html#disclaimer-about-non-standard-syntax) before using this proposed syntax feature with Prettier.

<!-- prettier-ignore -->
```js
// Examples
{
  using obj = g(); // block-scoped declaration
  const r = obj.next();
} // calls finally blocks in `g`
```
