treewide: change cargoSha256 with SRI hash to cargoHash

[Aleksanaa]

Description of changes

Treewide command:

find . -type f -name "*.nix" -print0 | xargs -0 sed -i 's/cargoSha256 = "sha256-/cargoHash = "sha256-/g'

There are some exceptions, basically using a wrapped builder, or writing in let. I've manually fixed them. Would be better to check again.
