This change adds a command that can be used to see the difference in
API between two gopls versions. It prints out the changes in a way that
can be copy-pasted into the release notes.
Also, only run the copyright test with 1.18. I wanted to do this before
to use filepath.WalkDir, but now it also doesn't work with generic
syntax (it doesn't use packages.Load, so doesn't respect build tags).
