See the explanation here: https://github.com/AdguardTeam/SafariConverterLib/issues/20#issuecomment-2532818732

We can use if-top-url (or even better - support if-frame-url in Safari 18) to support domain wildcards.

Rules that can be properly supported now:

• ||example.org^$domain=google.*
• ||example.org^$domain=/.*\\.org/
• google.*##body
• [$domain=/.*\\.org/]##body

Important things to check

1. Also check if it can be supported in Safari 17 just in case.
2. Check that we don't mix if-top-url and unless-*
