Feature #18146: Add `delete_prefix` and `delete_suffix` to `Pathname`

Pathname has sub method, but does not have the methods mentioned in the title.
Pathname may be able to provide delete_prefix and delete_suffix like String#delete_prefix and String#delete_suffix added in Ruby 2.5

This is an idea I got from feedback on RuboCop Performance.
