yarn: updated to 1.22.21

v1.22.21

Warning

This release is missing a couple of artifacts (the .msi/.rpm/.deb/.asc files); \ 
we're working on fixing this.
Fixes an issue in the v1.22.20 when calling Yarn from a project subfolder, \ 
outside of a Corepack context.

Added a SKIP_YARN_COREPACK_CHECK environment variable to skip the Corepack check.

v1.22.20

Warning

This release is missing a couple of artifacts (the .msi/.rpm/.deb/.asc files); \ 
we're working on fixing this.
Important: Punycode is now embed within the bundle, as it has been deprecated by \ 
Node.js and will be removed in a future version.

A message will be displayed when Yarn 1.22 notices that the local project has a \ 
package.json file referencing a non-1.x Yarn release via the packageManager \ 
field. The message will explain that the project is intended to be used with \ 
Corepack.

The yarn-error.log files won't be generated anymore, as we don't process \ 
non-critical 1.x bug reports (we however process all bugs reported on \ 
https://github.com/yarnpkg/berry; we just released the 4.0.2 release there).

The yarn set version x.y.z command will now install the exact x.y.z version \ 
(prior to this change it used to first install the latest version, and only in a \ 
second step would it downgrade to x.y.z; this was causing issues when we bump \ 
the minimal Node.js version we support, as running yarn set version 3.6.4 \ 
wouldn't work on Node 16).

Prevents crashes when reading from an empty .yarnrc.yml file.
