Fixed Checkstyle Issues

[dariuszzbyrad]

This PR addresses various Checkstyle issues by ensuring that all missing Javadoc comments are added and improving the Checkstyle configuration to properly handle documentation-related rules.

Summary of Changes:

• Javadoc Fixes: Added missing Javadoc comments for methods, fields, and types. Specifically:
  • Added @param, @return, and @throws tags where applicable.
  • Corrected incorrect use of @inheritDoc tags for static methods.
  • Updated Javadoc formatting to align with project standards.

Additional Context:

• The errors seen in the build were caused by a previous commit (e530765), which inadvertently introduced some violations in Javadoc documentation.

Example Fix for Static Method:

Before:

/** {@inheritDoc} */
public static DigitalOutputBuilder newInstance(Context context) {
    return new DefaultDigitalOutputBuilder(context);
}

After:

/**
 * Creates a new instance of {@link DefaultDigitalOutputBuilder} with the specified context.
 *
 * @param context the context used to initialize the digital output
 * @return a new instance of {@link DigitalOutputBuilder}
 */
public static DigitalOutputBuilder newInstance(Context context) {
    return new DefaultDigitalOutputBuilder(context);
}

This fixes the invalid @inheritDoc tag usage and provides a detailed description of the method's behavior.
