Incorrect inflection when using an underscored '_fee' or 'taxes'

[mrship]

Describe the bug

• When using pluralize for things like property_fee you get property_ves.
• When singularising taxes you get taxis

To Reproduce

#!/usr/bin/env ruby

require 'bundler/inline'

gemfile do
  source 'https://rubygems.org'
  ruby '3.3.4'

  gem 'dry-inflector'
end

require 'dry-inflector'

inflector = Dry::Inflector.new

puts "**** Incorrect inflection"

puts "pluralize: 'payment_provider_fee' => #{inflector.pluralize("payment_provider_fee")}"
puts "pluralize: 'payment_fee' => #{inflector.pluralize("payment_fee")}"
puts "pluralize: 'property_fee' => #{inflector.pluralize("property_fee")}"
puts "singularize: 'taxes' => #{inflector.singularize("taxes")}"

puts "**** Corrected inflection"

fixed = Dry::Inflector.new do |i|
  i.plural("payment_provider_fee", "payment_provider_fees")
  i.plural("payment_fee", "payment_fees")
  i.plural("property_fee", "property_fees")
  i.singular("taxes", "tax")
end

puts "pluralize: 'payment_provider_fee' => #{fixed.pluralize("payment_provider_fee")}"
puts "pluralize: 'payment_fee' => #{fixed.pluralize("payment_fee")}"
puts "pluralize: 'property_fee' => #{fixed.pluralize("property_fee")}"
puts "singularize: 'taxes' => #{fixed.singularize("taxes")}"

Expected behavior

• That a something_fee is pluralised as something_fees
• That taxes is singularised as tax, not taxis

My environment

• Affects my production application: YES (although we can workaround it)
• Ruby version: 3.3.4
• OS: macOS/Ubuntu
