fix: add evil-collection to overrides

[roman]

When installing nix-doom-emacs on a macOS m2 machine (Ventura 13.4), the build process hangs when processing the evil-collection package.

Adding this override fixes the problem.

CI is failing with

       (stack trace truncated; use '--show-trace' to show the full trace)

       error: fcitx-engines is deprecated, please use fcitx5 instead.

Does anyone know where is this coming from?

I think I encountered that some months ago, it's a matter of updating the flakes & unrelated to this PR, and since the other checks are happy I'm merging.

I pushed a hotfix directly to master running nix flake lock to generate the missing evil-collection lockfile entry which flake-compat relies on.

We should've caught it in the review, but it happens :P

Gosh, apologies about that 😞
