Changed target branch to staging and rebased due to number of rebuilds.

hooks/default change no longer necessary since #247245

Just rebased with staging to be sure, but it still fails to cross compile wrap without this, with the same error

[Artturin]

Sorry I forgot that my pr only fixed splicing python3Packages.callPackage { python }: while the hook splicing within the set (used by callPackage) is still broken and will eventually be fixed by #228139

the rebuilds are a bit weird so i'll check why that is happening

[Artturin]

I checked and there's really no rebuilds, rebuild count is likely just because of a rebase gone wrong
