Revert "Add bundletool to DEPS and remove outdated header comment (#28040)" (#28128)

This reverts commit 589b6a20.

DEPS

-# This file contains the dependencies used by the Engine repo.
+# This file is automatically processed to create .DEPS.git which is the file
+# that gclient uses under git.
 #
-# Use the `gclient sync` command to download and sync local checkouts
-# with the versions listed in this file.
+# See http://code.google.com/p/chromium/wiki/UsingGit
+#
+# To test manually, run:
+#   python tools/deps2git/deps2git.py -o .DEPS.git -w <gclientdir>
+# where <gcliendir> is the absolute path to the directory containing the
+# .gclient file (the parent of 'src').
+#
+# Then commit .DEPS.git locally (gclient doesn't like dirty trees) and run
+#   gclient sync..
+# Verify the thing happened you wanted. Then revert your .DEPS.git change
+# DO NOT CHECK IN CHANGES TO .DEPS.git upstream. It will be automatically
+# updated by a bot when you modify this one.
+#
+# When adding a new dependency, please update the top-level .gitignore file
+# to list the dependency's destination directory.
