Manage this Node.js package with version 3.6.0 of Yarn

done with version 1.22.19 of Yarn:

```Shell
yarn --version
```
```
1.22.19
```

```Shell
yarn set version -- 3.6.0
```
```
warning package.json: No license field
➤ YN0000: Retrieving https://repo.yarnpkg.com/3.6.0/packages/yarnpkg-cli/bin/yarn.js
➤ YN0000: Saving the new release in .yarn/releases/yarn-3.6.0.cjs
➤ YN0000: Done in 0s 668ms
```

afterwards, Yarn honours the setting `yarnPath` in its configuration
file `.yarnrc.yml`:

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

Yarn does not support the extension `*.yaml` for its configuration file.

The setting `packageManager` in `package.json` admits a checksum. In
this case, a checksum is not necessary, because Yarn is committed to the
repository.
