[PATCH 2/2] rebase: `preserve` is also a pull option, tell dying users

["Philip Oakley via GitGitGadget" <gitgitgadget@gmail.com>]

From: Philip Oakley <philipoakley@iee.email>

The `--preserve-merges` option was removed by v2.35.0. However
users may not be aware that it is also a Pull option, and it is
still offered by major IDE vendors such as Visual Studio.

Extend the `--preserve-merges` die message to direct users to
this option and it's locations.
