Add JSDoc type annotations to selectPing function

[Lang-Qiu]

Background

The public exported function selectPing in tgui/packages/tgui-panel/ping/selectors.js was missing type annotations. Adding JSDoc type annotations improves code readability, maintainability, and facilitates better integration with TypeScript or other type-checking tools without altering functionality.

Changes

• Added JSDoc type annotation to the selectPing function, specifying the state parameter as object and the return type as any.

Verification

Since this change only adds comments and does not modify the function's logic or API, it should be safe. You can verify by:

1. Running existing tests to ensure no regressions.
2. Checking that the code still executes as expected in the application.
3. Optionally, using a linter or TypeScript compiler (if configured) to confirm type annotations are correctly formatted.
