Nix commands respect Ctrl-C	9687 6995	7245

Previously, many Nix commands would hang indefinitely if Ctrl-C was pressed while performing various operations (including nix develop, nix flake update, and so on). With several fixes to Nix's signal handlers, Nix commands will now exit quickly after Ctrl-C is pressed.

This was actually released in Nix 2.20, but wasn't added to the release notes so we're announcing it here. The historical release notes have been updated as well.
