feat: allow specifying the binary to launch neovim in tests

[mrcjkb]

Use case: Run tests for neovim derivations packaged with Nix.

See also:

• Neovim (and maybe vim): v:progpath is set to the unwrapped executable NixOS/nixpkgs#78033
• tests: add test with nixpkgs.wrapNeovim mrcjkb/haskell-tools.nvim#93 (comment)

thanks :)

haha you were so fast ! I will try to check if generating a binary wrapper of neovim fixes that. It's a bit annoying since I like to peek at the wrapper but it could be optional at first, just to unblock you.

It's always nice to meet fellow NixOS users 😁

Not sure I follow what you mean. Generating a binary wrapper instead of a shell script wrapperr in pkgs.wrapNeovim?
