stackage.nix nightly since ghc 9.10.1 references unknown ghc-toolchain

[dten]

nightly references ghc-toolchain since ghc 9.10.1

https://github.com/input-output-hk/stackage.nix/blob/master/nightly-2024-12-11.nix#L599

but there is no such package https://hackage.haskell.org/package/ghc-toolchain

I assume this is supposed to be a reference to the package within ghc

https://gitlab.haskell.org/ghc/ghc/-/tree/ghc-9.10.1-release/utils/ghc-toolchain

this is the error that I get trying to use those nightlies right now
