Function ends_with_href

pub fn ends_with_href(text: &str) -> bool

Returns true if the given text string ends with a valid href attribute opener.

An href attribute looks like this: href="http://example.com",. so we look for href=" at the end of the given string.

Spaces are allowed to exist in between the href, =, and ". In addition, the quotation mark is optional, and can be either a single or double quote, so this function takes those into account as well.
