Print lockfile contents earlier

Currently, the lockfile gets printed after `bundle install` finished. This could be too late when `bundle install` fails for whatever reason.

I have a workflow that failed like this:

It would help to print the lockfile for this I think. It fetching version 0.0.1 confused me but probably the lockfile looks ok. New output:

```

```

So it's relatively at the top and not hidden somewhere. Also removes the need to check for the lockfile again.
