[java] Add serialVersionUID to TimeoutException to avoid serialization warnings

[seethinajayadileep]

💥 What does this PR do?

Adds an explicit serialVersionUID to the UrlChecker.TimeoutException class.

Since TimeoutException extends Exception, it is implicitly Serializable. Declaring a serialVersionUID prevents compiler/IDE serialization warnings and ensures a stable serialization identifier if the class structure changes in the future.

🔧 Implementation Notes

A serialVersionUID field with value 1L was added to the TimeoutException class.

private static final long serialVersionUID = 1L;

This follows common Java best practices for classes that implement Serializable (directly or indirectly through inheritance).

No behavioral changes were introduced.

💡 Additional Considerations

This change is purely a code hygiene improvement and does not modify runtime behavior. No additional tests or documentation changes are required.

🔄 Types of changes

• Cleanup (formatting, renaming)

@seethinajayadileep I think it's better to disable such warnings. Nobody is ever going to serialize TimeoutException - or any other exceptions - in Selenium project.

Thanks for the clarification. My intention was to address the serialization warning since TimeoutException extends Exception. But I agree that if Selenium doesn't rely on Java serialization for exceptions, this change may not be necessary. I'm happy to close the PR if preferred.
