Rails 8.1 deprecated `AbstractAdapter#check_if_write_query()` method, which breaks compatibility of this library

Problem

Rails 8.1 deprecated AbstractAdapter#check_if_write_query() method, which breaks compatibility of this library.

The original method code is this:

  def check_if_write_query(sql)
    return unless preventing_writes? && write_query?(sql)

    raise ActiveRecord::ReadOnlyError, "Write query attempted while in readonly mode: #{sql}"
  end

You can reimplement the same method for the 8.0-related adapter, but only if it doesn't exist yet in the runtime from the AbstractAdapter.
