As discussed in [NixOS/nixpkgs#281669](https://github.com/NixOS/nixpkgs/pull/281669#issuecomment-1899451746), it might be more beneficial to disable the update checker
and prevent the users from being annoyed to update to a version that's
not yet built in Nixpkgs.
A builtin option for disabling the update checker does exist, however
it's buried very deeply within Vesktop settings and normal users may not
ever be aware of its existence — better to do it in Nixpkgs itself
pnpm 8.10.0 introduced a feature that allows downloading npm deps for
other platforms. Sadly, this is a package.json option currently, but
using a simple patch with jq we can leverage this feature, to have a
single output hash for all supported platforms for our pnpm
dependencies. This might be one step forward towards an eventual
fetchPnpmDeps build-support function.
