Fix domain components for second-level domains in RDAP

[nazywam]

Hey, It's me again 😅

I think the current implementation of _get_domain_components might be broken for second-level domains.

For example, given the domain: impots.gouv.fr it will output:

print(client._get_domain_components("impots.gouv.fr"))'
('impots.gouv.fr', 'impots', 'fr')

As a result, whodap will be launched with: self.whodap_client.lookup("impots", "fr") and will, de facto, perform a query for impots.fr instead of impots.gouv.fr.

I think removing the TLD suffix for domain cores should work but let me know if you'd rather resolve this differently.

Welcome back 😅!

I tested your changes and your logic is definitely what was originally intended. I think the use of .removesuffix and domain_core is perfectly fine -- I can't think of any edge cases where this would fail.

Thanks again for your expertise and contributions 🫡
