Berry: [Feature] Local cache files should be removed when upgrading a package

[arcanis]

Describe the user story

I'm a user; I always forget to run yarn cache clean, and I see little point to do it manually because Yarn should know that the old files aren't needed anymore after a package upgrade.

Describe the solution you'd like

Yarn should simply clean the unused cache files when it detects that new packages have been added to the project (probably not when nothing changed).

``js repro const {readdirSync} = require(fs`);

await packageJsonAndInstall({
dependencies: {
'object-assign': '3.0.0',
},
});

expect(readdirSync(.yarn/cache)).toHaveLength(2);

await packageJsonAndInstall({
dependencies: {
'object-assign': '4.0.0',
},
});

expect(readdirSync(.yarn/cache)).toHaveLength(2);

```

@arcanis I'm sorry for pinging on this closed issue, but I've watched your talk about actions on YouTube a few times and am super interested in how you created this action. Do you have the action somewhere you can share? I'd like to use a "special code fence" to pull out some code from a github issue as well!

@loganpowell you mean Sherlock? It's developed here: arcanis/sherlock 🙂

@arcanis YES! 🙏 🙏
