[java] Add nullness for interactions

[mk868]

User description

Description

In this PR I'm adding nullness annotations for classes:

• org.openqa.selenium.interactions.Coordinates
• org.openqa.selenium.interactions.Interactive
• org.openqa.selenium.interactions.SourceType - I also changed null to "none" as descried in the w3.org, this change should be safe to apply because SourceType.NONE has no uses in the code.

NullAway analysis: #14421

Motivation and Context

The JSpecify nullness annotations will give developers better exposure to potential problems with their code to avoid NullPointerExceptions.
Related issue: #14291

PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

🎫 Ticket compliance analysis 🔶 14291 - Partially compliant Compliant requirements: Add JSpecify Nullness annotations to Selenium framework code Improve IDE and static code analyzer support for null checks Non-compliant requirements: Annotations should specify which parameters and return values can be null (only class-level @NullMarked added, no specific parameter/return annotations) Requires further human verification: Enhance interoperability with Kotlin (needs testing with Kotlin codebase)

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Score
Possible issue	Add null validation for type Consider adding a null check in the constructor since type is now used for all enum values including NONE. This prevents potential NullPointerException when the enum is used. java/src/org/openqa/selenium/interactions/SourceType.java [30] private final String type; +private SourceType(String type) { + if (type == null) { + throw new IllegalArgumentException("Type cannot be null"); + } + this.type = type; +} + Apply this suggestion Suggestion importance[1-10]: 8 Why: The suggestion is highly relevant as it adds crucial null validation to prevent potential NullPointerException, especially important since the PR changes NONE's value from null to "none" and adds @NullMarked annotation.	8
