bug: icons for lock files are inconsistent

[Tygo-van-den-Hurk]

• Eza version: v0.20.11 [+git]
• Eza command: eza --icons=always

Not sure if this is intended behavior but there is an inconsistency with the icons of flake.lock vs Cargo.lock etc. If you run eza --icons=always you get the following output for flake.lock and flake.nix:

 flake.lock  flake.nix

While Cargos lock-file does match the Rust icon:

 Cargo.lock  Cargo.toml

and so does npms lock-file:

 package-lock.json  package.json

Shouldn't this be:

 flake.lock  flake.nix

Then?
