Shift away from the phtml template

[captn3m0]

The phtml template method breaks separation of concerns and is not clean (using str_replace for templating is bad because PHP is a templating language by itself)

Alternative Solution:

1. Embed a javsacript snipped via a .js file in the codebase that is injected on our page using wp_enqueue_script
2. The only parameter needed when we call the script is pageId, so we embed a tiny snippet in the template that does it safely.

<button id="rzp-quick-btn" data-pageID="<?echo $pageId;?>"></button>

The event handler is attached via the script injected
