This test verifies the behavior of textDocument/prepareRename - we prompt with the full package path.

-- go.mod --
module golang.org/lsptests

go 1.20

-- b/b.go --
package b //@ preparerename("b", "golang.org/lsptests/b")

-- a/other.go --
// We prompt with the full package path, but changing a package directory is disabled when the package name does not match its directory base name. 
package other //@ preparerename("other", "golang.org/lsptests/a")
