Make theme installable

[MichaelCurrin]

Hi. I'd like to suggest making changes to the repo and to the docs to allow the theme to be installed as an external theme, in addition to the process of forking and installing as per the Install instructions.

This would require some changes in the code like adding to .gemspec:

  s.metadata["plugin_type"] = "theme"

And maybe making the name lowercase so match other gems.

  s.name = "dumbarton"

See Minima for example https://github.com/jekyll/minima/blob/master/minima.gemspec

Regarding how to actually install, I've tried this so far based on other projects.

Gemfile

source "https://rubygems.org"

gem 'Dumbarton', git: 'https://github.com/tcbutler320/Jekyll-Theme-Dumbarton'

I ran bundle install which also installed Jekyll 4.

$ ls vendor/bundle/ruby/2.7.0/bundler/gems/Jekyll-Theme-Dumbarton-6f6b0338a723
404.html       _config.yml         contributing.md     package.json
...

Config

Then I set my config value but get an error.

My config

theme: Dumbarton

Jekyll::Errors::MissingDependencyException: The dumbarton theme could not be found.

Or

theme: Jekyll-Theme-Dumbarton

Jekyll::Errors::MissingDependencyException: The jekyll-theme-dumbarton theme could not be found.

Hey @MichaelCurrin sorry to leave you hanging on this! Yes this is something I want to implement, I will likely take a look into theses suggestions and work on a solution later this month.
