## Description
The lockfile currently does not end with a newline at EOF. Text files
should [end with a newline](https://unix.stackexchange.com/a/18789).
This also lets you manually edit the lockfile in vim without 'fixeol'
creating a spurious change for the added newline.
This change however will create a change in users' lockfiles adding a
newline upon updating, but since the lockfile would be changing anyways
to update lazy.nvim itself, this is likely acceptable.
