Pushing tags indeed helped extract sources. But build fails due to 
incompatibilities with upstream files

I think Praveen locked the dependency on tar-fs to version 1.x in 
https://salsa.debian.org/js-team/node-yarnpkg/-/commit/8f44f7d238f4330b89d3b62c2cc369bb909459a6

I'm unsure if that's because upstream yarn mentions 1.x tar-fs as 
dependency or because there are other dependencies to 1.x tar-fs.

The API of tar-fs doesn't change between 1.x and 2.x, but the 
dependencies do. And the dependencies we have in debian make it such 
that 1.x doesn't work.

I tried following GroupSourcesTutorial and gbp manual. It is becoming 
very confusing for me with many version numbers and tags floating 
around. So I'll have to leave this here for possibly Praveen to pick up.
