nimsuggest: Instead of checking for protocol version 3 exactly, check for version 3 or later. (#22945)

Refactored the way nimsuggest checks for protocol version 3. Instead of
checking for version 3 exactly, it now checks for version 3 or later.
This way, once a version 4 is introduced, it will use version 3 as a
base line, and then extra changes to the protocol can be added on top.
