Add --no-pager flag to brakeman

[jaydorsey]

I followed the configuration/setup for Ruby, and have the following lefthook.yml config:

---
pre-commit:
  commands:
    brakeman:
      run: bundle exec brakeman

I noticed that brakeman "gets stuck":

I tried a number of flags (parallel, output, debug, bundler, no bundler, etc.) but I think the cause is the default paging behavior which the brakeman docs note here:

By default, Brakeman pages output to the terminal with the less pager. To have Brakeman output directly to terminal, use brakeman --no-pager

I thought this might be a useful improvement to the docs in case anyone else runs into this

I'm running macOS Mojave, brakeman 4.6.1 (via gem install), lefthook 0.6.3 (via gem install), ruby 2.6.3

Thank you @jaydorsey. This is a good point.
