Remove unnecessary dependencies from Groonga installation guide

Remove KyTea and ZeroMQ (libzmq) installation steps from the PGroonga
setup documentation. These dependencies are not required for using
PGroonga with IvorySQL.

- KyTea: Rarely used and not required even with release-maximum preset
- ZeroMQ: Only required when using Groonga via groonga-suggest-httpd,
  not needed when using Groonga through PGroonga

Tested and confirmed that PGroonga works correctly without these
dependencies in both package installation and source build scenarios
on AlmaLinux 9 with IvorySQL 4.6 and PostgreSQL 17.6.
