Improve CLI Output and Logging

[EficodeRjpalt]

This issue tracks the following improvements to the CLI output and logging:

• Add an ASCII art representation of a shining sun to the CLI output when displaying weather information.
• Remove INFO level log statements from WeatherApp.java and WeatherService.java to reduce log verbosity.

Example of new output:

    \\   /
     .-.
-- (   ) --
     `-'
    /   \\

Current Weather for [CityName]:
-------------------------------------
Weather for [CityName]:
Temperature: [Temp]C
Conditions: [Conditions]

Removed Logs:

• LOGGER.log(Level.INFO, "Weather request for city: {0}", city); in WeatherApp.java
• LOGGER.log(Level.INFO, "Getting weather data for city: {0}", city); in WeatherService.java
• LOGGER.log(Level.INFO, "Successfully retrieved weather data. Temperature: {0}°C", weatherData.getTemperatureCelsius()); in WeatherService.java
