UrlReplacer di kotonaiyo

[Honestly just testing the publishing process. Very much still WIP ;)]
Currently supports 2 sites:

1. https://docs.microsoft.com/*
If the AddOn detects a URL that starts with "https://docs.microsoft.com/" and is followed by a language code that is not "en-us", the AddOn replaces the language code with "en-us"
Example: "https://docs.microsoft.com/de-de/dotnet/csharp/" -> "https://docs.microsoft.com/en-us/dotnet/csharp/"

2. https://www.youtube.com/*
If the AddOn detects a URL that starts with "https://www.youtube.com/" and is followed by "shorts", the AddOn replaces "shorts" with "watch" to automatically change from youtubes shorts placer to the regular video player.
Example: "https://www.youtube.com/shorts/epQVrt4gliI" -> "https://www.youtube.com/watch/epQVrt4gliI"
