Manage this Node.js package with version 3.6.0 of Yarn

[Version 16.20.0 of Node.js][Node.js changelog 16.20.0], released on
2023-03-29, ships with version 0.17.0 of [Corepack][Node.js 16
Corepack]; see the corresponding [pull request][GitHub repository
nodejs/node PR 46842].

3.6.0 is the latest version of Yarn at this time.

As stated in the [README][Node.js Corepack 0.17.0 README], a checksum
should be specified:

> The hash is optional but strongly recommended as a security practice.

Version 0.17.0 of [Corepack][Node.js 16 Corepack] uses the function
`createHash` of the [Node.js module `node:crypto`][Node.js 16
node:crypto]; see
https://github.com/nodejs/corepack/blob/v0.17.0/sources/corepackUtils.ts#L138-L140.
The hash/hashing algorithms that function supports "[…] is dependent on
the available algorithms supported by the version of OpenSSL on the
platform". I chose [SHA-512][SHA-2] because it strikes the best balance
between safety/security and availability, as far as I know.

after setting `packageManager` in `package.json` with that checksum:

```Shell
corepack yarn --version
```
```
3.6.0
```

There's no difference between calling `corepack yarn` and calling the
`yarn` shim installed by `corepack enable`; both are the same:

```JavaScript
require('./corepack').runMain(['yarn', ...process.argv.slice(2)]);
```

the .js file is not committed and `yarnPath` is not set:

indeed,
