Changes:
- Updated `build-static-content` to parse `<meta>` tags from HTML
generated from a Markdown file, instead of the Markdown file. Parsing
them after the Markdown is converted to HTML will prevent any `<meta>`
tags inside code blocks from being seen as a `<meta>` tag containing
information about the page because angle brackets inside code blocks are
changed into HTML entities (`<` & `>`) when the Markdown is
converted to HTML.
