[Pkg-javascript-devel] please bring yarnpkg back to testing

[Paolo Greppi]

#960120 is keeping yarnpkg out of testing; there are two ways to resolve this:

1. work with upstream to fix this mess (not likely to happen as upstream seems unresponsive)

2. revert the changes that caused the issue; the last successful salsa CI pipeline I can find is this one:
https://salsa.debian.org/js-team/node-yarnpkg/-/commit/877478d5ef3f8a7564cdea211e5cd794fdfb97b5
so just revert all changes to this repo and the build deps to this status

I urge those who caused the mess fix it.
