fix: useId instead of random number for tooltip ID

Summary

Related Issues or PRs

Alternate approach to #2562, which does not change the API of the Tooltip component. Use React's useId to generate a unique identifier instead of a random number.

This is the expected way to generate IDs, so plays nicely with server side rendering frameworks and is easy to mock for unit or snapshot tests.

Example of jest config for mocking

// Make sure the auto-generated IDs are stable for snapshot testing
jest.mock("react", () => ({
  ...jest.requireActual("react"),
  useId: () => "r:id",
}));

How To Test

This is a pure bugfix/refactor. It makes no change to API or UI
