Update Tailwind config to look at Markdown files; adjust Matt Stauffer post style (#263)

* Update Tailwind to search markdown files for Tailwind styles to include

Some previous blog posts used Markdown styles, but they were only able to use styles that were already used in `.html` pages. This will allow styles to be defined in a blog post (Markdown) and Tailwind will build them, even if they don't exist anywhere else.

* Update Matt Stauffer intro post to bring back original styles
