docs(useThrottle): clarify defaultValue initial value description

[wo-o29]

Overview

This PR improves the documentation of the useThrottle hook by explicitly clarifying that the options.edges property's defaultValue represents the initial value.

While the defaultValue attribute already indicates the initial value, for users new to react-simplikit and its docs, it may not be immediately obvious visually.

Therefore, this description adds a clear note that the initial value is ['leading', 'trailing'] to enhance usability and maintain consistency with other documentation styles in the codebase.

Before	After

This change follows the documentation style exemplified in the useLoading Docs.

Checklist

• Did you write the test code?
• Have you run yarn run fix to format and lint the code and docs?
• Have you run yarn run test:coverage to make sure there is no uncovered line?
• Did you write the JSDoc?
