default configuration not distributed with the gem

[afeld]

Background Information

@tbaxter-18f and I noticed that the _config.yml values weren't being inherited from the released version(s) of the gem. Turns out that when you specify path: in the Gemfile, it picks up all those local files, but when released, it's only including the files and folders here:

uswds-jekyll/uswds-jekyll.gemspec

Line 13 in e93b9ab

s.files = `git ls-files -z`.split("\x0").select { |f| f.match(%r{^(assets|_layouts|_includes|_sass|LICENSE|README)}i) }

Implementation Steps

• [ ]

Acceptance Criteria

• Configuration inherited by sites using the theme as a released gem

To elaborate, theme config inheritance was added in Jekyll 4.0.
