feat(plugin-yarn): add support for yarn berry

[favna]

Standards checklist:

• The PR title is descriptive.
• The PR doesn't replicate another PR which is already open.
• I have read the contribution guide and followed all the instructions.
• The code follows the code style guide detailed in the wiki.
• The code is mine or it's from somewhere with an MIT-compatible license.
• The code is efficient, to the best of my ability, and does not waste computer resources.
• The code is stable and I have tested it myself, to the best of my abilities.
• If the code introduces new aliases, I provide a valid use case for all plugin users down below.

Changes:

• This updates the yarn plugin to better support Yarn berry (aka Yarn v2 and beyond) because some commands are no longer available or changed in modern Yarn.
• A new pair of aliases yii and yifl are added. These are to install dependencies while locking versions down to the yarn.lock file. The reason yifl is an alias for yii is to respect that for v1 it's yarn install --frozen-lockfile, whereas for berry it's yarn install --immutable, so yii.
• The aliases ydlx and yn are added to cover yarn dlx and yarn node

Version checking inspired by the git plugin

yarn --version is a really slow command. In my tests it was around 150ms for v1 and 300ms for v4.
We can't add 300ms in startup, it'd make it really slow.
I like the idea though, and I propose using a zstyle config for it, like global-path

I'm not familiar with this. Can you provide a resource? Also, do you mean that through a zstyle the user would configure if they want the Yarn v1 or Yarn Berry set?

[carlosala]

Yep, I mean exactly that. You can see an example in yarn plugin precisely, the config is called global-path. Here you have the zsh manual! https://zsh.sourceforge.io/Doc/Release/Zsh-Modules.html#The-zsh_002fzutil-Module
