Refactor handle_plural_values() to simplify whitespace handling when parsing plural values

[lil-aditya]

The handle_plural_values() method previously used a manual loop to remove leading whitespace from values after splitting the string by ;.

The implementation looked like this:

values = plural_value.split(";")

Remove trailing leading whitespace

for i in range(len(values)):
current = i + 1
if current < len(values):
clean_value = values[current].lstrip()
values[current] = clean_value

This approach had a few issues:

It only removed leading whitespace (lstrip) and not trailing whitespace.

It unnecessarily used an index-based loop, making the code more complex than needed.

The logic skipped the first element and only cleaned subsequent ones.

Python provides a more concise and readable way to perform this operation.
