Move /[book] page to /[book] and /[book]:[bookHadith]

[thecashewtrader]

Currently, in the book page, we are manually checking for a : and splitting, rendering different versions of the page. If we split the route into two: /[book] and /[book]:[bookHadith], it would vastly simplify the pages, in addition to allowing for easier implementation of <title> tags, OpenGraph embeds, etc.
