Issue Description and Traceback

I have identified a bug in the plural_s function within the pandapower project. The issue arises when attempting to pluralize a word based on a given number. The current implementation provides an incorrect pluralization when the number is greater than 1. The expected behavior is to return an "s" when the number is greater than 1, indicating the plural form, but the current implementation returns an empty string when the number is less than 1 but "s" when 1 or less.

This pandapower network includes the following parameter tables: -- bus (7 element) -- load (1 elements) -- sgen (1 elements) -- gen (1 elements) -- switch (8 element) -- shunt (1 elements) -- ext_grid (1 elements) -- line (4 element) -- trafo (1 elements)

In code this is where the bug is:

def plural_s(number):
    if number > 1:
        return ""
    else:
        return "s"

Supposed to be:

def plural_s(number):
    if number > 1:
        return "s"
    else:
        return ""

Expected Behavior

The expected behavior is to return an "s" when the number is greater than 1, indicating the plural form, but the current implementation returns an empty string when the number is less than 1 but "s" when 1 or less
