Level: Rewriting History 7 - "The Truth"

This would be the same as level 6 "An Easy Level" #260 , but you have to make the changes manually instead of doing `git rebase -i`

The "truth" is that rebasing is really just checking out the branch or commit, then cherrypicking

Make the log messages form the sentence "This is an easy level"

`git gud status`
```
======= Simulating: git log --oneline --reverse
This
easy
an
is
level
<<<<<<<
```

`git gud status` (after interactive rebase)
```
======= Simulating: git log --oneline --reverse
This
is
an
easy
level
<<<<<<<
```
