[lagobot] ensure default nixpkgs commit by deleting the commits from devbox.json (#834)

## Summary

We want to ensure that the default Nixpkgs commit that we use works with
all
Lagobot example projects. So, we delete the nixpkgs commit hash from the
devbox.json.
When the testscript will execute `devbox run run_test`, the default
nixpkgs commit
hash will be added to the devbox.json and used.

## How was it tested?

tests should pass in buildkite
