Move to yarn 2+

[paoliniluis]

Newer yarn version works way faster than the one we have right now (v1). We should move to Yarn v2 once shadow-cljs supports it

thheller/shadow-cljs#670

Faster for which tasks?
Can you please provide some examples and/or benchmark results?

Tested it locally on my machine and the "yarn install" command was ~ half of what's right now. Didn't measure it though, but trust me it's faster

Performance is not the only reason to upgrade though - this page covers it well: Why should you upgrade to Yarn Modern?.

@kamilmielnik, what features of Modern Yarn are interesting to you?

[paoliniluis]

Just tested yarn v4 and it mostly works, it fails only in the licencing step not being able to find the script, which should be a simple fix
