Deprecation warning: "rustPlatform.rust.cargo is deprecated. Use cargo instead." May be easy fix, but...

... my Nix expertise is still not quite there yet. I just sense it's probably an easy reference change in the nix recipe. The full warning is actually:

trace: warning: rustPlatform.rust.cargo is deprecated. Use cargo instead.
trace: warning: rustPlatform.rust.rustc is deprecated. Use rustc instead.

It seems to be coming from the firefox-overlay.nix file (thanks for that work, btw!)

Did you have any joy with this? Seeing similar with LibreWolf, which makes sense as it's a Firefox fork.

I can't see anything in this overlay that would cause either of you to have that error. only pkgs/servo/default.nix uses those attrs but that file is not called anywhere and has other errors.
