Add IDN Homograph Domains to blocklist.yaml

[glaubermagal]

You might be wondering why "ɡithub.com" is blocklisted. The answer is: it's not the real github.com, though they look similar. Still unsure? Try comparing "ɡithub.com" === "github.com" in your browser console—you'll see it returns false.

Using domains with mixed scripts for malicious purposes is called IDN Homograph Attack. It is a very advanced type of attack – and I plan keep adding relevant homograph domains here from now on, so we will help prevent people from being deceived by them.

I used a tool I created, EvilURL, to analyze the actual github.com domain. I discovered a concerning issue: some registrars allow domains with mixed character sets, enabling bad actors to create domains that look nearly identical to legitimate ones. And this malicious domain "ɡithub.com" is registered and leading to a malicious website.

Please follow me on github and give a start to my repo. This will help me keeping improving my Cybersecurity tool.
