hub: fix incorrect hash

[k2nr]

Motivation for this change

I'm new to Nix so correct me if I misunderstand something. When I tried to install hub I got the below error:

output path ‘/nix/store/r5v6p7zh6av5y7m50vgb0ksqwh2psmiq-hub’ has r:sha256 hash ‘1vswkx4lm6x4s04453qkmv970gjn79ma39fmdg8mnzy7lh2swws6’ when ‘0iwpy50jvb8w3nn6q857j9c3k7bp17azj8yc5brh04dpkyfysm02’ was expected
cannot build derivation ‘/nix/store/wgnqdzxv2lp2rr94s7n2d6jxbmhnr69a-hub-2.2.3.drv’: 1 dependencies couldn't be built
