doc: mention GIT_SEQUENCE_EDITOR and 'sequence.editor' more

From: Philippe Blain <[email protected]>

The environment variable GIT_SEQUENCE_EDITOR, and the configuration variable 'sequence.editor', which were added in 821881d88d ("rebase -i":
support special-purpose editor to edit insn sheet, 2011-10-17), are mentioned in the git config man page but not anywhere else.

Include config/sequencer.txt in git-rebase.txt, so that both the environment variable and the configuration setting are mentioned there.

Also, add GIT_SEQUENCE_EDITOR to the list of environment variables in git(1).
