This commit includes several improvements and refactoring to the
77_UWZ.pm file. The primary changes involve unifying language
handling by replacing direct comparisons of the country code with
a call to a new utility function, `contains_string`, which checks
if the `CountryCode` exists within an array. This change enhances
the readability and maintainability of the code.
Additionally, certain code cleanup has been performed, including
minor formatting adjustments for better alignment and spacing,
removing deprecated warning pragmas, and correcting the 'Mäy'
month name spelling in the English months array.
These changes do not introduce any breaking changes, but they
improve the overall structure and consistency of the code, making
future modifications and updates easier.
