docs: enhance useKeyboardState SEO (#959)

## 📜 Description

Improved SEO for `useKeyboardState` hook.

## 💡 Motivation and Context

I found that people use this search:

<img width="572" alt="image"
src="https://github.com/user-attachments/assets/adee299b-7897-42e0-b26b-0e5994586e61"
/>

And don't get results. In reality we have a hook that do that, jsut
under a different name: `useKeyboardState`. In this PR I'm fixing it by
adding more keywords to this page.

## 📢 Changelog

<!-- High level overview of important changes -->
<!-- For example: fixed status bar manipulation; added new types
declarations; -->
<!-- If your changes don't affect one of platform/language below - then
remove this platform/language -->

### Docs

- added more `keywords` for `useKeyboardState` page;

## 🤔 How Has This Been Tested?

There is no way to test it until google re-indexes the page.

## 📝 Checklist

- [x] CI successfully passed
- [x] I added new mocks and corresponding unit-tests if library API was
changed
