atom: 1.42.0 -> 1.48.0

[chkno]

And atom-beta: 1.43.0-beta0 -> 1.49.0-beta0

This version bump includes an important python2 -> python3 update:
node-gyp 3.7.0 -> 5.1.0 in Atom's apm/package-lock.json, which, per
nodejs/node-gyp#1687, finally allows python3
to be used instead of EOL'd python2 for atom-package installation.

Motivation for this change

Be able to install atom packages without installing python2, which is 5 months past EOL.

Things done

• Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
• Built on platform(s)
  • NixOS
  • macOS
  • other Linux distributions
• Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
• Tested compilation of all pkgs that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
typora and termius-app debs could not be fetched. I didn't look into this further because these only build with allowUnfree.
• Tested execution of all binary files (usually in ./result/bin/)
• Determined the impact on package closure size (by running nix path-info -S before and after)
  1301740784 -> 1308167848 ( +0.5% )
• Ensured that relevant documentation is up to date
• Fits CONTRIBUTING.md.

Note that there is another open Atom version bump PR: #83340 1.42.0 -> 1.45.0.
(Atom needs to get to 1.48 to fix the python2 problem.)

Reviewed points

• package name fits guidelines
• package version fits guidelines
• package build on x86-64
• executables tested on x86-64 (only for atom, atom-beta, apm, apm-beta, nix-tour and teams)
• all depending packages build: compilation of hyper-haskell, termius and typora fail (also fail on master)

Possible improvements

use a different environment for compiling atom and electron

Comments

There is a lot of useless rebuild due to atomEnv also being used to compile electron. It may be a good idea to build electron with it's own environment.
