We can't ignore example lockfile but also can't commit it

[aaronmondal]

Surely there is some workaround.

• Ignoring examples/flake.lock causes direnv/devenv to break
• Committing it would break downstream users because the relative reference to rules_ll via ../ is not reproducible across machines (for different users the absolute path to the directory is different).
• Usually one would use git update-index --skip-worktree for this, but that doesn't work with devenv.

What a dilemma lmao.

For now I've sent https://github.com/eomii/rules_ll/pull/67, but that's hardly a satisfactory solution.
