gettext build failure on aarch64-linux

[gepbird]

I was surprised to see gettext-0.22.5 failing as it builds on hydra, then I looked at the .drv file and realised it's using 0.20.1's source due to https://github.com/nix-community/neovim-nightly-overlay/pull/738/files#diff-1caf8284fc09be57558dfe827e26c9d57d395c7a1b93a57130f514ee6e653ab1L35-R38

Looks like this is another gcc 14 failure.

Edit: I updated flake A which uses flake B which uses neovim-nightly-overlay, then I tried to build flake A. Flake B's nixpkgs is overridden with flake A's (updated) nixpkgs, but neovim-nightly-overlay wasn't updated, causing this issue 🤦

Yes, this is why I had to remove the override. Right now, we are building neovim with nixpkgs' 0.22.5 gettext. As it seems to work fine, we can keep this solution for now.
Once neovim will bump their gettext version to 0.22.5, we can resume overriding the src.

I will leave this issue open as a reminder to re-enable the override whenever possible.
