element-{desktop,web-unwrapped}: {fix,modernize} update script 

- Does not fetch `-rc` versions anymore
- Fixes weird output by `prefetch-yarn-deps` (see https://github.com/NixOS/nixpkgs/pull/407704#issue-3069691545)
- Doesn't create any temporary files anymore, since everything is
  prefetched local builds will be faster too
- DRY
