Improves types in useTabs hook

[joshfarrant]

ℹ️ This is a follow-on PR from #1137. It will be rebased from main and marked as ready-for-review once that PR has been merged. It is also blocked by #1146 as that PR fixes a bug in the Tabs component where aria-labelledby wasn't being passed through to the useTabs hook.

Summary

Improves types in useTabs hook, improves useTabs tests, and fixes an accessibility issue in the IDE component which these type improvements automatically highlighted.

List of notable changes

• Fixes incorrect onClick, onKeyDown, and onFocus types
• Enforces that either a label or labelledBy is passed to getTabListProps()
• Updates the focusTab function to only focus the element and nothing else. onFocus will handle the state updates. Previously two duplicate state updates were being triggered.
• Generally makes typings in the hook more accurate
• Removes @ts-expect-error from useTabs.test.tsx, now that the types are fixed
• Adds a missing label to the tablist in the IDE component (thanks, TypeScript! 🎉)

What should reviewers focus on?

• Check out the test tweaks
• Make sure you're happy with the type changes to useTabs. There are no changes to functionality, just types.
• Make sure you're happy with the new tablist label in the IDE component.
