fix(nix): refresh npmDepsHash for the electron-builder bump

The value #244 left behind describes the dependency set before electron-builder
moved to 26.15.3, and that upgrade re-resolves a lot: 7zip-bin, app-builder-bin,
dmg-license and iconv-corefoundation drop out while pkijs, asn1js, unzipper and
@noble/hashes come in, because upstream moved code signing off vendored native
binaries onto JS. So the recorded hash no longer matches and `nix build` fails
outright for anyone installing through that channel.

Taken from the Nix job's own output on this branch rather than computed blind.
