Add more web domains #5

[Antoineio]

Hello 👋,

I am opening this PR to resolve #5

I moved TLDs to a separate file (tlds.go) for better maintainability
This refactor allowed me to update the Domain() function to use the extracted TLDS list dynamically instead of hardcoded values

I also updated the TestDomain() function to also use the TLDS list

Finally, i added a new test, TestTLDsLength(), to validate TLD lengths
I added this test because, while researching the most commonly used TLDs, i came across RFC 1035, which states that a label must be a maximum of 63 characters. While adhering to this standard is not mandatory, but i believe it's a good practice 🤷‍♂️

Let me know if any adjustments are needed. 🙏

I didn't know about RFC 1035, a link with more info could be added to the code as a comment, feel free to direct commit that change. Thanks again!
