Initial identifier paragraph custom renderer implementation

What does this MR do?

Replace render_identifier_text.js with render_identifier_paragraph to simply the parsing and identifying of identifier syntax. With this update the inline code exception of the previous solution is embedded as we interpret the text at a higher level (paragraph) vs. as the lowest level (text).

Technically speaking the prior solution is more robust (due the text granularity and non-dependence of new lines to constitue a paragraph), but this solution is much simpler, easier to maintain, and debug.
