[VOL-5297] Add more pre-commit linters.

.pre-commit-config.yaml
-----------------------
  o Document where the latest config file can be copied from.
  o [todo] install this as a git submodule -- lf/pre-commit.

bin/setup.sh
------------
  o Greatly simplify the installer.
  o No longer need to preserve makefiles/ when transitioning.
  o Git submodule installed into lf/onf-make/ so simply
    mkdir and git submodule <path>.

Makefile
--------
  o Added convenience makefile target view used to
    pre-screening README.md markdown edits before publishing
    to the repository for final rendering/browser viewing.
