java.starlark.net: rename com.google.devtools.starlark This change renames the Java packages of the Starlark interpreter and REPL command. The Bazel team owns the domain starlark.net, and the Go implementation lives at go.starlark.net; the Java packages should use java.starlark.net. There are no immediate plans to publish the interpreter as a public API or to run a web server at that domain, but it will save pain later if we rename the classes only once. Now that the Starlark interpreter's production code no longer depends on any Bazel packages (except serialization, which cannot be broken until we implement byte compilation), we will soon make the following moves: lib.syntax (frontend) -> net.starlark.java.syntax lib.syntax (evaluator) -> net.starlark.java.eval lib.skylarkinterface -> net.starlark.java.annot PiperOrigin-RevId: 312126212
