I worry this will have further consequences, as I believe we depend on this function for Nemesis as well.

I would rather remove usage of scylla-enterprise product in this particular query, though I am not sure if it wont cause problems for upgrades from older versions

is_enterprise method is used in many places, probably this change will break many tests, including unit tests, upgrade, features tests (for which 2025.1 is considered as enterprise) and possibly more.

If it breaks only this web test, let's hardcode product_type in web_install_scylla.
