Description
Previously, MarkdownSanitizer sanitizes symbols used in URLs, despite Discord ignoring them and not treating them as markdowns.
The algorithm implemented searches and replaces all URLs by a placeholder, and replaces them back after the majority of the MarkdownSanitizer#compute method finishes.
A dedicated method had also been added to the MarkdownTest class to efficiently test this algorithm.
