Do not replace timeskip when it is in a URL

[wtfparadox]

Description

A bug occurs in the show notes when a URL contains a text formatted like a timeskip. In this scenario, the text should not be replaced, as it will break the URL.

Fixes #145

What is done

I wrote a method that checks whether a potential timeskip is in a URL by finding the nearest HTML closing tag to the potential timeskip.
I have also written a new test that checks the exact string the issue occurred on.

Checklist

• In "Rebuild - Tatsuhiko Miyagawa" episode 325 text formatted like timeskip is not replaced by timeskip
• In "Foundation - True Ventures" episode 8, timeskips work properly
• Should this change be included in the release notes? If yes, please add a line in CHANGELOG.md
• Have you tested in landscape?
• Have you tested accessibility with TalkBack?
• Have you tested in different themes?
• Does the change work with a large display font?
• Are all the strings localized? I havent touched any string resources
• Could you have written any new tests?
• Did you include Compose previews with any components? I havent used compose
